    Why readExplains how URI transient caching in WordPress JSON API Auth allows unauthenticated attackers to steal admin cookies.

    WordPress JSON API Auth plugin versions up to 3.1.2 contain a critical authentication bypass via cached session cookies (CVE-2026-97637). Transient caching in the parent PI-Media/json-api plugin caches endpoint responses ignoring HTTP methods, letting unauthenticated GET requests pull active admin cookies from previous POST responses.

    Why readBlock unauthenticated access to GetSimple CMS password reset endpoints due to predictable PRNG seeding causing full account takeover.

    GetSimple CMS 3.3.22 contains an unauthenticated password reset flaw that overwrites user password hashes with a temporary password upon request. Because the temporary password relies on PHP rand() seeded with microtime(), the entropy space is sufficiently small to allow real-time brute force attacks against unthrottled login endpoints, leading to complete administrator account takeover.

    Why readFlaws in ThreadX Module Manager enable unprivileged modules to execute privileged writes and disable MPU protections.

    ThreadX Module Manager misvalidates object pointer locations, allowing modules to treat internal allocation offsets as valid control blocks. Attackers can leverage kernel helper routines to perform privileged memset operations across arbitrary memory and clear MPU boundary flags.

    Why readUnbounded heap writes in LevelX NAND flash metadata parser allow control-flow hijacking via overwritten function pointers.

    Mounting a crafted NAND flash image triggers an out-of-bounds heap write in LevelX lx_nand_flash_open(). Attackers can overwrite driver function pointers to achieve arbitrary instruction pointer execution. Header comments indicate parts of the vulnerable parser were generated by Copilot.

    Why readUnvalidated trace callbacks in ThreadX user-mode modules allow privilege escalation to kernel mode.

    User-mode memory-protected modules issuing kernel calls in ThreadX builds with trace logging enabled can register arbitrary function pointers as global trace callbacks. The kernel executes the registered callback without validation when the trace buffer wraps. Runtime captures confirm execution at kernel privilege level.

    Why readUnauthenticated heap buffer overflow in NetX Duo TFTP server caused by missing upper bound validation on DATA datagrams.

    The NetX Duo TFTP server implementation fails to check upper bounds on incoming packet lengths before passing them to FileX file write routines in nxd_tftp_server.c. An unauthenticated attacker can send oversized DATA datagrams to force FileX to copy beyond single packet boundaries, triggering a heap buffer overflow.

    Why readNetX Duo WebSocket client memory corruption enables arbitrary code execution via crafted split frames.

    NetX Duo's WebSocket client resets its unmasking cursor to the initial packet when processing chained packet buffers. A server frame split across packets forces the unmasking XOR loop into memory containing control blocks. Attackers can control the corruption using four-byte WebSocket masking keys.

    Why readMemory disclosure vulnerability in NetX Duo DTLS parser echoes process memory in ServerHello packets.

    A length validation bug in NetX Duo DTLS ClientHello handling compares cipher suite length against total record length instead of remaining payload bytes. An unauthenticated peer can force an out-of-bounds read of up to 255 bytes that are reflected directly into the ServerHello response, disclosing adjacent heap memory.

    Why readUnauthenticated RTSP server packet pool exhaustion DoS in NetX Duo caused by unreleased error buffers.

    When parsing malformed Session headers in RTSP requests, NetX Duo returns raw error codes directly rather than mapping them to RTSP status codes. This skips packet cleanup logic in _nx_rtsp_server_error_response_send, leaking response packets and draining the global server packet pool after a handful of requests.

    A security researcher uncovered an authentication flaw in Microsoft's internal Titan analytics API hosted on Azure Cloud Services. Because the service failed to validate JWT signatures on login tokens, unauthorized administrative SQL queries could be issued against backend databases holding trillions of rows. Microsoft has since patched the flaw.

    watchTowr reconstructs CVE-2026-88772 in the NetScaler DTLS handling path, reachable before any authentication, and uses the teardown to argue that the hardened security appliance posture is mostly branding. This is primary research with enough technical detail to build detection or confirm a patch actually closes the path, and it follows a companion post on a second NetScaler issue the same week. Given the exploitation history of internet facing NetScaler Gateway, treat it as a patch now item rather than a reading item.

    Why readA clean two-bug chain that goes from unauthenticated request proxying to full Kubernetes namespace takeover, and a reminder that regex is the wrong tool for blocking private IP ranges.

    Bishop Fox found that Zilliz Attu 2.6.5 exposes an unauthenticated proxy endpoint, and that the regex intended to block requests to private addresses can be bypassed. Chained, the two give an attacker arbitrary server side requests from inside the cluster, which the researchers rode to complete takeover of the Kubernetes namespace in a cloud deployment. Attu is the web UI for Milvus, so anyone running a vector database stack should assume it is reachable and move to 3.0.0.

    Why readA /dev/cuse node inside a container image passes through gVisor's gofer to the host, turning a sandbox boundary into host root code execution.

    In Google gVisor before commit 573a9e73cf844f, the host file helper (gofer) fails to restrict a CUSE character device node included in a container image: opening it reaches the real host device. An attacker who can deploy container images into a sandbox can register a host device and abuse CUSE's unrestricted ioctl handling to overwrite root udev helper memory, achieving root execution on the host. Only Linux hosts with CUSE enabled are affected, but the whole point of gVisor is that this should not be possible.

    Why readZammad before 7.1.2 binds SSO identities to local accounts on the provider-reported email alone, so anyone with an Azure AD tenant can log in as an existing agent or admin.

    With "Automatic account link on initial logon" enabled, Zammad matches an incoming third-party identity to a local account by email address without checking that the identity provider verified ownership of it. Because Zammad ships a multi-tenant Microsoft 365 /common app registration by default, an attacker who controls any identity in any Azure AD tenant can set that identity's email to a victim's address and authenticate as them, bypassing the local password entirely, including for administrators. Zammad now honours the xms_edov ID token claim and treats a missing claim as unverified; fixed in 7.1.2.

    Why readFourteen real Java vulnerabilities that were fixed upstream, sometimes years ago, but never got a CVE, which means your scanner has been calling affected versions clean.

    Chainguard has published the first batch from its Athena programme: 14 silent vulnerabilities in Java projects, one critical, one high, eight medium and four low, all already fixed at HEAD and all absent from vulnerability databases. Patches are in a public repository and four of the more serious cases are walked through in the post. The broader point is the class of bug rather than this batch, since silent upstream fixes leave no signal for scanners and Chainguard says thousands more are queued behind these.

    Why readA race between QEMU's main thread and a 9pfs worker gives a malicious guest a path out of the shared directory and, from there, host code execution as the QEMU user.

    Concurrent Tlcreate and Twalk requests in QEMU's 9pfs subsystem trigger a use-after-free that lets a guest user craft a fid path containing stale heap data. That bypasses the directory traversal restrictions and escapes the shared directory boundary, giving arbitrary host file read and write and ultimately code execution as the QEMU process user, which is a full VM escape. Relevant to anyone using 9p/virtio-9p passthrough for guest filesystem sharing.

    Why readShows concretely why Postgres RLS is not access control: row policies constrain which row you update, not which columns, and Capgo's SSO trust anchor was left writable.

    Capgo through 12.261.0 shipped migration 20260826100000 with a BEFORE UPDATE guard freezing only dns_verified_at, domain, status and enforce_sso, leaving provider_id, metadata_url and attribute_mapping writable while the table is granted ALL to anon and authenticated. An org_admin holding org.update_settings can PATCH provider_id over PostgREST to an IdP they control, then authenticate through it while asserting the org owner's email, and the merge routine attaches their SSO identity. The column-level gap in an RLS-only model is the transferable lesson here.

    Why readUnauthenticated SQL injection in Piwigo through 17.0.0beta1 with no fixed version available, reachable through the public search flow whenever rating is enabled.

    An unauthenticated guest can call pwg.images.filteredSearch.create with a crafted ratings[] value and then open the returned search URL. include/ws_functions/pwg.images.php stores the value unvalidated into the search rules, and include/functions_search.inc.php integer-casts only the lower rating bound while concatenating the raw upper bound straight into SQL, giving error-based and blind extraction plus time delays. No patched release existed at time of publication, so internet-facing galleries need rating disabled or the endpoint blocked.

    Why readA confused-deputy in Capgo: a scoped write API key makes a service-role worker rewrite private storage objects it cannot touch directly, and there is no patch.

    PUT /app/:id accepts a user-controlled icon value and stores it in public.apps.icon_url without checking the path belongs to that app's image namespace. The update fires the on_app_update trigger, whose worker calls cleanStoredImageMetadata() under supabaseAdmin() and re-uploads the referenced object with upsert: true, so an app-limited key can overwrite out-of-scope private images such as an organization logo despite Storage RLS. All versions affected; no fixed version existed at advisory time.

    CVE-2026-28326 is a hardcoded static key in SolarWinds Access Rights Manager: the same client-authentication secret ships with every install, so anything that can reach TCP 55555 gets to a .NET deserialization sink. Bishop Fox confirmed execution as NT AUTHORITY\SYSTEM and released a detection tool that fingerprints a vulnerable asset with two safe requests. SolarWinds fixed it in 2026.2.1.7 on 17 September 2026 and rated it 8.8 on an adjacent-network vector; since ARM is the software deciding who can open which mailbox and file, audit how far port 55555 actually reaches before trusting that AV:A.

    Why readEvery Pake-generated desktop app accepts IPC from any HTTPS origin, and Tauri's ACL never checks app-registered commands, so untrusted page script can call download_file.

    Two inherited template settings combine: capabilities/default.json grants IPC with "remote": {"urls": ["https://*.*"]}, and "withGlobalTauri": true in tauri.conf.json puts window.__TAURI__.core.invoke() in reach of ordinary page JavaScript. The sharper finding is that Tauri's access control list only gates plugin: commands; commands registered through generate_handler! are never checked, so they need no permission entry and get none. Pake registers download_file that way, which is why any script in the wrapped site can drive native functionality.

    Why readNetdata's setuid-root ndsudo helper can be pointed at an attacker-controlled UNIX socket whose reply reaches pickle.loads(), giving root on any host with fail2ban-client installed.

    Before 2.10.4, the `fail2ban-client-status-socket` command in `src/collectors/utils/ndsudo.c` accepts a `--socket_path` supplied by the low-privileged netdata service account. Because fail2ban's `CSocket.receive()` in `fail2ban/client/csocket.py` deserialises the socket response with pickle.loads(), a malicious socket turns the root-run client into arbitrary code execution as root. The chain is a clean example of a setuid helper trusting a caller-controlled path into an unsafe deserialiser; fixed in 2.10.4 and nightly 2.10.0-782, and Netdata plus fail2ban is a common pairing on internet-facing Linux hosts.

    The handler in src/reachy_mini/daemon/app/routers/apps.py depends only on Depends(get_app_manager) and checks no credential, so any caller can supply an AppInfo body naming a Hugging Face Space. install_package in src/reachy_mini/apps/sources/local_common_venv.py then installs it via uv or pip, running the package's own build and setup code. Reach depends on _resolve_bind_host in daemon/app/main.py: the wireless model binds 0.0.0.0, everything else binds loopback, which is why the vector is AV:A rather than fully remote.

    asn1rtt_ber:dec_subidentifiers/3 and its PER equivalent asn1rtt_per_common:dec_subidentifiers/3 accumulate base-128 subidentifiers with (Av bsl 7) + H into an unbounded integer, making each continuation byte linear in the bits already accumulated and the whole decode quadratic. A single arc of about 262 KB of continuation bytes costs roughly 13 seconds of CPU on typical hardware, and the JER helper asn1rtt_jer:json2oid/1 has the same unbounded-integer parsing from dot-separated JSON OIDs. The vulnerable decoder is generated into every ASN.1 module containing an OBJECT IDENTIFIER, which puts it in the TLS handshake path of anything built on OTP. CVSS 8.2, remote and unauthenticated.

    Why readOrigin reflection plus Allow-Credentials on open-vsx.org's /user/ endpoints let any web page mint a publish-capable personal access token for a logged-in extension publisher.

    The open-vsx.org deployment returned Access-Control-Allow-Origin reflecting the requesting origin alongside Access-Control-Allow-Credentials: true on authenticated /user/ endpoints, exposing /user, /user/tokens, /user/namespaces, /user/extensions and namespace member lists to any origin. Because /user/csrf was readable the same way, CSRF protection on write endpoints fell too, so an attacker page could call /user/token/create and exfiltrate a token with publish and delete rights over the victim's namespaces. The headers came from the CDN/edge layer rather than the application, which sets allowCredentials(true) only against a single exact origin from ovsx.webui.url; the interesting part is that no software configuration produced the flaw, and the same class of edge-layer override applies to anyone fronting a credentialed API with a CDN.

    Why readThe fix for CVE-2016-15059 introduced a heap use-after-free in Net::IDN::Punycode, triggered by decoding an attacker-supplied label.

    decode_punycode in the XS backend computes the insertion pointer before growing the output buffer, and the realloc updates every pointer except that one, so the subsequent move and code point write go through freed heap. The buffer starts at twice the label length and any code point above U+FFFF takes four output bytes, so a label of such code points reliably forces the reallocation. Versions 2.301 up to 2.590 are affected, the pure-Perl backend is not, and 2.301 was itself the CVE-2016-15059 fix.

    Why readEvery rejected punycode label leaks twice its length in heap from Net::IDN::Punycode's XS backend, with no valid input required.

    decode_punycode in the XS backend allocates the return scalar before validating input, sizing it at twice the input length, and frees it only on the success path. All three croak paths that reject a label therefore leak the scalar and its buffer, and nothing bounds label length in the to-Unicode direction because the 63-byte DNS limit is checked only when encoding to ASCII. Versions 2.302 up to 2.590 are affected; a remote sender can grow a long-lived Perl process until it dies.

    The vulnerability-scan endpoints scripts/lua/rest/v2/add/host/to_scan.lua and schedule_vulnerability_scan.lua take scan_ports without an admin gate and validate it only with validateSingleWord, which allows shell metacharacters; vs_utils.lua then concatenates it into nmap_scan_host and runs it through ntop.execCmd, execCmdAsync or popen. Any non-admin account gets OS command execution as the ntopng process user wherever nmap is installed.

    Before conda 26.5.2, parse_entry_point_def in conda/common/path/python.py accepted an unvalidated entry-point command from a package's info/link.json, and PrefixPathAction.target_full_path joined it to the prefix without checking the result stayed inside bin or Scripts. Path separators, traversal segments or an absolute path let create_python_entry_point write a wrapper anywhere the parent directory already exists, or clobber an in-prefix entry point that later executes attacker Python as the installing user.

    vm2's rejection sanitizer (hostPromiseSanitizeReject, makeSanitizedPromiseCallback, normalizeHostPromiseCallbacks in lib/bridge.js) only wraps then/catch rejection slots holding a function, and the Symbol.species neutralization is installed solely on the sandbox intrinsic Promise.prototype, so host-realm Promises are untouched. Sandboxed code overwrites p.constructor[Symbol.species] and calls p.then() with no onRejected handler; V8 substitutes its internal Thrower, re-throwing the raw host rejection value into an attacker-captured closure. If that value is host-pivotable, for example a host process object, the result is arbitrary code execution on the host. Applies wherever an embedder exposes a host API returning a host Promise.

An attacker harvests candidate userId values from the public booking bootstrap and GET /api/tenants/[id]/appointments/staff-public-keys, injects a controlled key, then uses the login check comparing verificationResult.userId against the email-resolved account as an oracle to confirm the match and obtain a STAFF session.

    lib/builtin.js matches negative denylist entries by exact module name, so a config of builtin: ['*', '-fs', '-child_process'] blocks fs but not its subpaths, and node: prefix handling is inconsistent enough that -node:fs/promises fails to block the bare form. Host file creation and writing were confirmed through fsp.writeFile(), with cp, mkdir, rename, rm and the read operations equally reachable. Fixed in 3.11.7; anyone still using vm2 as a security boundary for untrusted code should audit their builtin wildcard configuration now.

Because censored defaults to false, stored records include raw cookies (the Grav session cookie value is the PHP session id, so an admin session can be resumed), the full parsed request body (login posts data[username] and data[password], and Clockwork's password filter only inspects top-level keys, so passwords sit in plaintext), and the entire system and plugin configuration.

    GravExtension::assertSandboxDumpSafe() calls SandboxExtension::isSandboxed() with no Source argument, which reports only the global sandbox flag Grav never sets, so the guard from GHSA-mc5q-6hpj-rp7j is dead code and print_r, vardump, json_encode, yaml_encode and string stay reachable. print_r reflects the real Config object held in a private property of the SandboxConfig facade, defeating that facade's path redaction and exposing SMTP credentials, API tokens, webhook secrets and cache backend passwords. Affects 2.0.0-rc.1 through 2.0.21 and is fixed in 2.0.22, where the filters are registered with needs_is_sandboxed; Grav 1.7 has no Twig content sandbox and is unaffected.

    Sign-in verifies the JWT with Jwt.verify/4 and only revokes afterwards: MagicLink.SignInPreparation revokes in a Query.after_action callback and MagicLink.SignInChange in an after_transaction hook that runs post-commit, so nothing serialises the validity check against consumption. TokenResource.Actions.revoke/3 writes the revocation as an upsert, meaning a concurrent duplicate revoke succeeds silently rather than conflicting and no request loses the race.

    Why readash_authentication's dynamic_oidc per-connection identity namespacing never actually takes effect, so whoever runs one IdP connection can sign in as a user established through a different one.

    The strategy is meant to write each UserIdentity row's strategy field as "<name>/<connection_id>", but __connection_id__ is only set on the ephemeral per-request struct built in dynamic_oidc/plug.ex, while DynamicOidc.IdentityChange.change/3 re-fetches the compile-time strategy through Info.strategy_for_action and gets the defstruct default of nil. OAuth2.identity_strategy_name/1 then falls back to the bare strategy name for both writes and the reads in oauth2/user_resolver.ex and oauth2/sign_in_preparation.ex. Because the identity resource's unique key is (uid, strategy), a single row exists per sub across every connection and the identity-match branch fires across tenant boundaries, which matters for anyone offering customer-managed OIDC connections.

    WebAssembly.compileStreaming and instantiateStreaming in vm2 3.10.1 through 3.11.6 return a raw host-realm Promise; by controlling Symbol.species through Promise.prototype.finally, sandbox code receives the raw host error object, walks from the host error constructor to the host Function constructor and recovers the real host `process`, gaining host module access such as fs. This bypasses the fix for GHSA-6j2x-vhqr-qr7q, which had removed the JSPI entry points WebAssembly.promising and WebAssembly.Suspending.

    In vm2 3.11.4 through 3.11.6 the NodeVM constructor tests requireOpts with typeof === 'object' && !== null, which an array satisfies, so the guard meant to reject nesting without explicit require configuration passes. makeResolverFromLegacyOptions() then returns a resolver holding only NESTING_OVERRIDE.vm2, letting sandbox code require the host vm2 module and construct an inner NodeVM with its own builtin allowlist such as child_process.

    vm2 3.11.6 identity-checks only the direct call target at lib/bridge.js:1624 when deciding whether to rebuild a rejected host Promise value, so `p.then.call(p, undefined, cb)` makes the intercepted target Function.prototype.call and the sanitiser never runs. Any embedder that bridges an async host function or a NodeVM external module method can leak a host error whose own properties reference host objects, for example `err.detail = process`, giving sandbox code `e.detail.mainModule.require('child_process')` and command execution at host privilege.

    On Node.js 26, vm2 3.10.2 through 3.11.6 allows sandboxed code to define an async function returning a Promise whose constructor carries an attacker-controlled Symbol.species; Promise.prototype.finally() then bypasses vm2's wrapper protections because V8 14.6 leaves the PromiseThenLookupChain protector stale. That yields the host Function constructor and process object and arbitrary code execution.

    Why readAn unprivileged local user on macOS gets root through Parallels Desktop 26.4.0 (build 57513) by abusing prl_disp_service's world-writable socket and argument injection in the appliance unpack path.

    JFrog chains three defaults in Parallels Desktop for Mac: a world-writable Unix socket, a local client login that trusts peer credentials rather than a Team ID, and an appliance extraction path that builds tar arguments via Qt string splitting. A quote in the parent path injects --use-compress-program=, and macOS tar executes the attacker's script as uid 0. Confirmed on 26.4.0 build 57513 on Apple silicon; any compromised unprivileged process or CI job on a developer Mac running Parallels is a root escalation away.

    Why readUse-after-free in the Linux crypto subsystem's async AEAD request handling (CVE-2026-31719) that escalates from low-privileged local code to kernel context.

    Unlike the neighbouring ZDI kernel advisories this one needs only the ability to run low-privileged code, which makes it a plausible container-escape and post-exploitation escalation primitive rather than a chain component. The flaw is a missing object-existence check when handling asynchronous AEAD requests, reachable from userspace crypto interfaces. Fixed upstream in commit 3bfbf5f0a99c; patch your kernels on the normal cycle and prioritise multi-tenant hosts.

    NVD ·3 Sep 2026 ·fetched 3 Sep 2026, 23:42 UTC Research CVE-2026-71380 CVSS 8.7 EPSS 0.4% agreed3/3

    Why readSlowloris by design in Erlang/OTP inets httpd: the request timeout is cancelled once headers parse, so a stalled body pins a worker forever across OTP 17.0 to 27.3.4.17.

    httpd_request_handler:handle_info/2 cancels the request timeout as soon as any parse step succeeds, headers included, and the more-data clause re-arms the socket with {active, once} without setting a new timer. httpd_request:whole_body/2 returns that continuation whenever received bytes fall short of the announced Content-Length, so a well-formed request that stops mid-body leaves the worker blocked indefinitely; the byte-rate reclaim only runs when minimum_bytes_per_second is configured, which it is not by default. Repeating across connections fills max_clients at negligible bandwidth cost. Fixed in OTP 27.3.4.17 and later branch releases.

    Why readCross-namespace IDOR in Goploy <= 1.17.5 lets any low-privileged manager rewrite another project's git remote URL, which becomes RCE on the next deploy; no patch exists.

    Project.AddFile, EditFile, RemoveFile and Project.Edit in cmd/server/api/project/handler.go take a row id straight from the JSON body, and model.ProjectFile.GetData and model.Project.GetData filter only on that id, with no namespace ownership check. A user with the manager role or FileSync/EditProject permission in their own namespace can therefore read, write and delete files in any project on the install, and set a foreign project's git remote to a repository they control; Edit runs git remote set-url, so the next deploy pulls attacker code. No public patch at time of publication, so restrict who holds those roles or take the instance off shared access.

    Why readTraefik's HTTP/3 server was built with no timeout at all, so the default 60-second read timeout never applies and an unauthenticated client can pin upstream connections open indefinitely.

    Bishop Fox found that Traefik's documented request read timeout is implemented as a deadline on the underlying TCP connection, which HTTP/3 does not use; the HTTP/3 server was constructed without any timeout, so the setting has no effect on that protocol. An unauthenticated remote user can hold requests open indefinitely, consuming one upstream connection per request until legitimate traffic is denied. Affects versions 2.8.2 through 2.11.55 and 3.0.0 through 3.7.11, which covers most container and Kubernetes ingress deployments running HTTP/3.

    Why readUnpatched out-of-bounds write in pdfforge PDF Architect's PDF parser giving remote code execution on opening a malicious file, disclosed as a 0-day with no vendor fix.

    Improper validation of user-supplied data during PDF parsing allows a write past the end of an allocated buffer and code execution in the context of the current process; the target must open a file or visit a malicious page. ZDI reported the bug on 02/20/26, the vendor acknowledged it on 03/23/26, and it was published unpatched after a 07/13/26 notice.

    In 4.4.0 through 4.14.6, the non-merged branch of update_master_files_in_worker() derives destinations from safe_join() alone, which keeps files inside /var/ossec but never checks they land in the directory declared by their cluster_item_key. The destination check that exists on the primary node and on the worker's merged branch was omitted, so a peer with the cluster key can drop files into paths executed as root; the delete branch has the same gap. This is the residue of CVE-2026-30893, which only blocked traversal outside /var/ossec. Fixed in 4.14.7, and worth prioritising because the cluster key is a shared secret many deployments treat casually.

The service's own authentication is ineffective because it relies on a hardcoded salt and accepts an all-zero wildcard MAC. EPSS is already 0.026, in the 84th percentile, and blocking UDP/9992 at the perimeter is the immediate mitigation where firmware cannot be replaced.

    NoInternalUrlRule in backend/app/Validators/Rules/NoInternalUrlRule.php resolves the hostname with gethostbyname() and blocks private ranges only at registration time; WebhookDispatchService then calls the stored URL through spatie/laravel-webhook-server with no Guzzle options set, so redirect following stays on and the resolution is never repeated. A destination that redirects to loopback, RFC1918 or the cloud metadata endpoint, or whose DNS record simply changes later, gets fetched by the server, and WebhookResponseHandlerService stores the response body where the requester can read it back from the webhook logs endpoint. The pattern generalises well beyond this product: SSRF filters that run at configuration time and not at dispatch time are not filters.

    Why readAn unauthenticated DUML command interface over Bluetooth lets anyone in range rewrite a DJI drone's Wi-Fi PSK and then reach the flight control interface.

    DJI drones accept unauthenticated DUML commands over Bluetooth that modify SSID, PSK, MAC address, regulatory country code and channel. Overwriting the PSK with a known value lets an attacker in Bluetooth range join the drone's internal Wi-Fi and issue flight commands, and crafted commands can also restart or disable the radios to cut control, video and telemetry mid-flight. Affected firmware is listed per model, including Neo before 01.00.0400, Flip before 01.00.1200, Air 3 before 01.00.1600, Mavic 3 Pro before 01.01.0700 and Mavic 4 Pro before 01.00.0500.

    Why readact's Artifacts V4 backend ships a hardcoded four-byte HMAC key and a commented-out run ID ownership check, and binds to the host's outbound address by default.

    Any workflow using actions/upload-artifact@v4 or download-artifact@v4 starts an HTTP backend whose CreateArtifact, GetSignedArtifactURL, ListArtifacts, FinalizeArtifact and DeleteArtifact RPCs accept a caller-supplied workflow_run_backend_id without verifying ownership: validateRunIDV4 in pkg/artifacts/artifacts_v4.go parses the value and returns it with the comparison left commented out. Signed URLs are authenticated with an HMAC keyed on the constant 0xba 0xdb 0xee 0xf0, identical in every build, computed over an unseparated concatenation of endpoint, expiry, artifact name and task ID, so signatures are both forgeable and ambiguous across differing name and task pairs. Because --artifact-server-addr defaults to the outbound interface rather than loopback, anyone on the same network as a developer running act can read, overwrite or delete artifacts.

    CVE-2026-76844 details a path traversal in webpack-dev-middleware's getFilenameFromUrl: UP_PATH_REGEXP applied to path.normalize(`./${pathname}`) only catches ".." standing as a complete path segment, while containment is tested with pathname.startsWith(publicPathPathname) and the file path is built from pathname.slice(publicPathPathname.length). With publicPath set to /assets and no trailing slash, a request for /assets../.env passes the guard because its dot-dot lives inside the segment "assets..", and the fixed-offset slice hands "../.env" to path.join. Reading the file requires a physical filesystem behind the middleware, meaning writeToDisk is true or a custom outputFileSystem is set, since the default memfs volume holds only build output.

    CliprdrStream_Read in libs/clipboard/src/windows/wf_cliprdr.c requests cb bytes of a remote file, then runs CopyMemory(pv, clipboard->req_fdata, clipboard->req_fsize) where req_fsize comes verbatim from the peer's CLIPRDR FileContentsResponse cbRequested field via wf_cliprdr_server_file_contents_response and is never clamped to cb. The only length check, req_fsize < cb, handles short reads and is evaluated after the copy has already happened, so a malicious peer answering a small read with an oversized response writes chosen data past the heap buffer of the OLE paste consumer, typically explorer.exe. Triggering it needs the local user to paste remote clipboard file contents, and since the code is a FreeRDP fork, other downstream forks are worth checking for the same pattern.

    DJI drones exchange DUML protocol messages with the DJI Fly app over unencrypted BLE, including the Wi-Fi credentials handed over when a client connects over Wi-Fi or the drone enters QuickTransfer mode. An attacker in BLE range captures the SSID, PSK and trusted-identifier UUID in cleartext, then joins the drone's internal network, reaches its exposed services, and decrypts traffic between the drone and its legitimate operator.

    The sync_command binary passes unsanitised input straight to a shell sink in command.lua, and the command execution path is enabled by default, so anyone who can talk to the MQTT broker gets arbitrary commands as root. Fixed in firmware 2.5.24.

    CVE-2026-8452 is a heap overflow in the SAML single sign-on parser on Citrix NetScaler ADC and Gateway, reachable pre-authentication in one HTTP request against any Gateway or AAA vserver with SAML configured, and it corrupts memory in the process handling all appliance traffic. Bishop Fox worked out that patch state is observable from the outside in one or two ordinary SAML exchanges, and released a checker covering both directions of the exchange, which matters because upgrading the build does not guarantee every virtual server picked up the fix. The post also lays out compromise indicators to hunt for and flags a crash signature that practitioners are likely to misread as evidence of an attack.

    Nebula through 1.2.0 reads out of bounds in Vlp32Decoder::unpack() when a datagram shorter than expected arrives on the Velodyne UDP sensor port, which unlike the other drivers applies no sender-address restriction. The decoder walks into adjacent heap memory and silently emits fabricated points into downstream PointCloud2 messages consumed by Autoware nodes, so the consequence is data integrity in a perception stack rather than a crash (CVSS 4.0 VI:H). Anyone running Autoware with Velodyne input should restrict the sensor port by source address and upgrade.

    z_vrfy_flash_copy() in drivers/flash/flash_util.c validated only the output buffer with K_SYSCALL_MEMORY_WRITE and passed src_dev and dst_dev through unchecked, unlike every sibling flash syscall which guards its device pointer. Because z_impl_flash_copy() dereferences those pointers and calls through their driver API tables (api->get_parameters, flash_read, flash_write), an unprivileged thread on a CONFIG_USERSPACE build can point them at a fake device in its own address space and choose the function pointers the kernel calls. Clean writeup of a trust-boundary omission, and a useful audit pattern for anyone reviewing syscall verifiers in RTOS code.

    watchTowr Labs walks through a pre-auth remote code execution flaw in Citrix NetScaler, tracked provisionally as CVE-2026-8452, on an appliance class that sits at the network edge and terminates SSLVPN sessions. The writeup is primary exploit research rather than advisory coverage, so it carries the reachability details and code path needed to judge whether your configuration is exposed and to build detection while you patch. NetScaler pre-auth bugs have a consistent history of moving from public writeup to opportunistic scanning quickly, and EPSS at the 40th percentile reflects only what has been seen so far, not what this becomes once the technique circulates.

    The flaw sits in dnsmasq's processing of DNSSEC NSEC and NSEC3 type bitmaps, where the loop lacks a proper exit condition and can be driven into an infinite loop. No authentication is required, and the result is denial of service on the affected installation. EPSS is only 0.072 but sits in the 93rd percentile; the practical exposure is embedded and appliance builds of dnsmasq that will patch slowly, if at all.

    CVE-2026-27654 is an integer underflow in NGINX's parsing of WebDAV requests handled under an alias directive: user-supplied data is not validated before a memory write, giving remote code execution in the context of the service account with no authentication. ZDI's advisory carries the technical root cause but no patch reference in the text supplied.

    Why readAn unauthenticated attacker can register their own ML-KEM-768 public key as an extra recipient for any tenant's encrypted appointments, and a JavaScript `undefined === undefined` comparison makes the bypass silent.

    OpenReception before 1.0.4 accepts attacker-supplied ML-KEM-768 public keys at POST /api/tenants/{tenantId}/staff/{staffId}/crypto without authentication: the handler logs an "Unauthorized crypto key storage attempt" warning when neither session nor registration cookie is present, then inserts the row anyway. That breaks the platform's claim that even administrators cannot read sensitive data, since the attacker becomes an additional decryption recipient for future patient appointments. A second variant suppresses even the warning: the Zod schema marks `email` optional, so omitting it with no registration cookie makes the check `registrationEmail === email` evaluate `undefined === undefined` to true and the request is treated as legitimate.

    In OpenReception before 1.0.2, POST /api/auth/register/{userId} checks that the WebAuthn challenge matches the registration cookie's email but never checks that the path `userId` belongs to that email. An attacker requests a challenge for their own address, completes the ceremony with their own authenticator, and replays the response against a victim's user ID; addPasskey writes the attacker credential into the victim's user_passkey rows and the next login as the victim's email issues them a session. Staff-list endpoints return user IDs to authenticated tenant members, so the identifier needed is not secret. The binding mistake generalises to any passkey enrolment flow.

The account is written with is_active=true and confirmation_state=ACCESS_GRANTED, skipping email confirmation and usable immediately for login and tenant enumeration.

    ZDI is publishing this as a 0day: the Q80's application installer fails to properly verify package signatures, so an attacker on an adjacent network segment can install and execute arbitrary code without authentication. CVSS 7.5, no vendor fix referenced at publication. Payment terminals sit in flat store networks and handle cardholder data, so the practical move is network segmentation and monitoring of terminal management traffic until PAX ships an update.

  200. CVE-2026-71319 (CVSS 9.6): Nuxt is an open-source web development framework for Vue.js. Prior to 3.3.1, Nuxt DevTools (development mode only) exposes a bidirectional RPC channel (opens in a new tab)

    NVD ·8 Aug 2026 Research CVE-2026-71319 CVSS 9.6 EPSS 0.3% agreed2/2

    Why readAny page that can reach a developer's Vite HMR port can chain two unauthenticated Nuxt DevTools RPC calls into arbitrary command execution on that developer's machine.

    Nuxt DevTools before 3.3.1 exposes a bidirectional RPC channel over the Vite HMR WebSocket (subprotocol vite-hmr) with no token, handshake, or origin check. updateOptions(), clearOptions(), and openInEditor() skip the ensureDevAuthToken check the other mutating methods enforce, so an attacker sets behavior.openInEditor to an arbitrary command via updateOptions() and then calls openInEditor() on any existing file, at which point the launch-editor package spawns it as a child process. Development mode only, but developer workstations hold cloud credentials and signing keys, and the missing origin check is what makes this reachable from a browser tab.

    Binarly (firmware) ·8 Aug 2026 Research agreed2/2

    Why readSignature verification in U-Boot SPL can be bypassed during FIT image processing, giving controlled code execution before the verified boot chain starts.

    A flaw in how U-Boot's Secondary Program Loader parses FIT images allows an attacker to get code execution while bypassing image signature checks, defeating verified boot on affected embedded configurations. The exposure is configuration-dependent, so whether a given board is affected turns on how its SPL and FIT setup is built. Upstream boot protections were hardened in response, anyone shipping U-Boot in a device with a root of trust should re-check their SPL config against the disclosed conditions.

    NVD ·8 Aug 2026 Research CVE-2026-71287 CVSS 8.8 EPSS 0.3% agreed2/2

    Why readCacti's ORDER BY allowlist keeps parentheses and dots, so `SLEEP(5)` survives sanitisation intact and any authenticated user gets blind SQLi.

    sanitize_sql_column() in lib/functions.php strips everything outside /[a-zA-Z0-9_().]/ to permit expressions like COUNT(id) and table.column, which means a function-call payload passes through unmodified into raw ORDER BY clauses that cannot be parameterised. The sort_column GET parameter reaches this sink in at least user_log.php, utilities.php, user_domains.php and user_group_admin.php, and privilege level is irrelevant, any logged-in user qualifies. Cacti is widely deployed on internal monitoring networks and has a track record of prior bugs reaching KEV, so treat authenticated-only as weak mitigation here.

    NVD ·8 Aug 2026 Research CVE-2026-71270 CVSS 8.6 EPSS 0.3% agreed2/2

    Why readStirling-PDF's `/api/v1/convert/url/pdf` endpoint missed the SSRF hardening its three siblings received, letting an attacker-supplied page pull cloud metadata into the output PDF.

    ConvertWebsiteToPDF.java validates only that the initially requested URL resolves to a public IP, then fetches the page server-side and hands the raw HTML to a WeasyPrint subprocess. WeasyPrint retrieves embedded resources, `<img src="http://169.254.169.254/...">` and the like, with no per-resource filtering, so internal endpoints and IMDS responses land in the generated PDF. The endpoint requires no authentication, and the html/pdf, file/pdf and markdown/pdf paths were fixed while this one was not, which is the more interesting lesson: SSRF fixes applied per-endpoint rather than in the fetch layer leave gaps.

    NVD ·8 Aug 2026 Research CVE-2026-71259 CVSS 8.6 EPSS 0.1% agreed2/2

    Why readAn `and`/`or` precedence bug in ESPHome's `cv.url()` validator lets a `file://` URL in `external_components` clone and execute arbitrary local Python.

    `if parsed.scheme and parsed.netloc or parsed.scheme == "file"` binds `and` tighter than `or`, so any `file:` URI passes validation regardless of netloc. That validator gates the `url:` field of the `external_components` git source schema, which is handed to `git clone`, git supports `file://` natively, and the cloned path is then registered with Python's import machinery by ESPHome's component loader. Processing a crafted YAML config with `esphome config` or `esphome run` therefore executes attacker Python; affects through 2026.7.0-dev, and shared or downloaded ESPHome configs are common enough in the Home Assistant ecosystem to make this realistic.

    NVD ·8 Aug 2026 Research CVE-2026-71272 CVSS 8.5 EPSS 0.2% agreed2/2

    Why readMemos validates a webhook's resolved IPs and then dials the original hostname, letting net.Dialer re-resolve it, a clean, reproducible DNS-rebinding TOCTOU bypass of SSRF protection you should check your own code for.

    CVE-2026-71272 (CVSS 8.5) breaks down safeDialContext() in internal/webhook/webhook.go: it calls net.DefaultResolver.LookupHost(), checks the returned addresses against reserved ranges, then passes net.JoinHostPort(host, port) rather than the validated IP to the dialer. DialContext performs its own lookup, so an attacker with control of a short-TTL record returns a public IP at validation time and an internal one at connect time. The fix pattern, dial the IP you validated, not the name, generalises to every SSRF guard written this way.

    Why readMagistrala's Rules Engine hands authenticated low-privilege users a Go and Lua sandbox that is not a sandbox: full stdlib including os and net/http, plus preloaded db, ioutil and HTTP libraries in Lua.

    The Go engine (re/golang.go) runs user scripts through the Yaegi interpreter with `stdlib.Symbols` and validates only with a regex blocking goroutines and `panic()`, leaving `os.ReadFile`, `os.WriteFile`, `os.Remove` and `os.Environ` reachable. The Lua engine (re/lua.go) validates nothing and preloads `db`, `ioutil`, an HTTP client and `filepath`. The result is arbitrary file read/write, environment-variable disclosure, direct database access and SSRF into internal microservices from an ordinary user account, a good case study in why interpreter-based rules engines need symbol allowlists, not regex denylists.

    Why readnanoMODBUS ≤1.23.0 lets a malicious Modbus server corrupt memory in the client via a Read Device Identification response, a reminder that client-side parsers in OT libraries are attack surface too.

    CVE-2026-71255 (CVSS 8.6) is an out-of-bounds write in recv_read_device_identification_res() (FC 0x2B / MEI 0x0E) in nanomodbus.c. The server-supplied object_length is validated only against remaining PDU size and never against the caller's buffers_length, so after strncpy the code writes a NUL terminator at buffers_out[buf_index][object_length]. When object_length ≥ buffers_length the terminator lands past the caller's buffer, corrupting adjacent stack or heap memory on the polling client.

    NVD ·8 Aug 2026 Research CVE-2026-71288 CVSS 8.8 EPSS 0.3% agreed2/2

    Why readKoha's guided report builder concatenates the `order_by` CGI parameter and a dynamically-named `{order}_ovalue` parameter straight into an SQL ORDER BY clause, giving any low-privilege library staff account blind SQLi against a database holding patron PII and LDAP credentials.

    CVE-2026-71288 (CVSS 8.8) traces the flaw through reports/guided_reports.pl, where multi_param('order_by') and the derived `_ovalue` parameter are appended verbatim to the query in C4::Reports::Guided with no allowlist or escaping. ORDER BY columns cannot be bound as placeholders, so an allowlist is the only defence and none exists. The create_reports or execute_reports permission, routinely granted to non-admin staff at libraries running Koha, is enough for time-based blind extraction of patron records and staff/LDAP credentials.

    Why readA single crafted Modbus TCP packet overflows FreeModbus's LINUXTCP receive buffer by seven bytes because of a > instead of >= bounds check.

    xMBPortTCPPool() in demo/LINUXTCP/port/porttcp.c tests usTCPFrameBytesLeft > MB_TCP_BUF_SIZE rather than >=, so an MBAP frame declaring Length 264 yields 263 bytes remaining and passes the check. recv() then writes up to 263 bytes starting at offset 7 into the 263-byte static aucTCPBuf, spilling seven bytes into the adjacent usTCPBufPos variable.

    CVE-2026-71236 (CVSS 8.7) sits in GetParsedAndFilteredRequestBody in controllers/Api/BaseApiController.php, where the entity encoding HTMLPurifier produced to neutralise markup is reversed on the purifier's own output. Live script tags are reconstructed and stored, then rendered elsewhere without re-sanitisation, giving stored XSS across products, recipes, stock, users, chores and other objects. Worth reading as a pattern: post-sanitisation "cleanup" of encoded output is a recurring way to defeat a correct sanitiser.

    sip_to_json() in modules/sipmsgops/sipmsgops.c memcpys a SIP header name into a 255-byte stack buffer using the full parsed length, while the SIP parser itself permits header names up to roughly 65000 bytes. Any deployment whose routing script calls sip_to_json() can therefore have its saved frame pointer and return address overwritten by a single unauthenticated datagram, giving a reliable crash and, on builds without stack protections, code execution. The affected range is 4.0.0 and prior with no patch at publication, so the immediate control is auditing routing scripts for sip_to_json() and filtering oversized header names upstream.

The pattern generalises to other OEM control-center software, which is worth auditing on any managed laptop fleet.

The precondition is Developer Mode or an enterprise sideloading policy being enabled, which is the exposure gate worth auditing and restricting. Detection moves to the network layer: the MSAppHost/3.0 user agent reaching anything outside Microsoft domains flags the whole class of hosts, not just this one sample, and should be paired with review of AppX registration activity.

The gain is largest on OT services, 11 percent to 97 percent, while false alarms against real services stay at 0.7 percent. PentestGPT and HackingBuddy fail the same way, so prior results showing honeypots derail AI attackers describe a prompting artefact rather than a durable defensive property.

    The paper builds a formal model for channel integrity under partially chosen state, with the SSH sequence number as the attacker-influenced input, and gives pseudocode for the eight most prominent AEAD modes used in SSH. By varying the send oracle it separates ciphertext-only (the original Terrapin vector), known-plaintext and chosen-plaintext settings and derives concrete security bounds for each mode. The result: all three Encrypt-then-MAC modes and ChaCha20-Poly1305 in SSH are insecure in this model, closing the open question of whether "unaffected by Terrapin" meant "secure".

    Why readThe target of an automated scan can forge the evidence that an exploit worked, and one rule predicts which checks are forgeable: whether the decision reads attacker controlled data.

    Across a four stage AI assisted testing pipeline, nine of fifteen confirmation mechanisms could be forged by the system under test, and forgeability was predicted entirely by whether the confirmation read attacker controlled content. The rule held prospectively on sixteen held out mechanisms and was 99.9 percent accurate across 12,203 mechanisms in public scanner templates, which means it applies to the template libraries most teams already run. The counterintuitive result is that deterministic rules were cheaper to forge than eight open weight LLM judges, failing at 2 percent of attacker controlled response content against a median of 50 percent, so the confirmations reported as fact are the weaker ones.

The harness compiles to a Syzkaller-compatible interface and is refined iteratively, sidestepping the brittleness of LLM-only generation under runtime nondeterminism and the failure of directed fuzzing to reach the vulnerable state at all.

    Prompted by the new HTTP Query method, Johannes Ullrich tested what common web servers actually do when a GET request carries a body. Apache 2.4.68 accepted a GET with Content-Length: 6, returned 200, and passed both CONTENT_LENGTH and the body content through to a CGI script; nginx did not forward it the same way and answered with a 301 instead. Any pair of components that disagree about whether a GET body exists is a place where a front end proxy and a back end can be made to read two different requests out of one byte stream, so the practical takeaway is to test your own chain rather than assume the standard settles it.

    Given a supersingular elliptic curve over F_p^2, the OneEnd problem asks for a non-scalar endomorphism, and by known reductions it also settles the supersingular endomorphism ring and isogeny problems that isogeny-based cryptography rests on. The algorithm fixes a family of smooth degrees in advance, uses counting results to guarantee many isogenies from curves to their Frobenius conjugates, and a collision estimate to show a random walk reaches one; it then splits a degree, enumerates two lists of shorter isogenies and matches targets. Crucially the analysis carries no smoothness heuristic, so the p^(1/3) exponent now holds unconditionally where it previously required an assumption, tightening the concrete security margin for isogeny-based schemes.

    The authors identify a directionality-based exfiltration class for analog and mixed-signal ICs: data-dependent circuit-offset modulation drives current back out through an input pin, requiring a closed-loop amplifier, an exposed amplifier input, and high impedance at that pin. They validate it on a photoplethysmography analog front-end fabricated in commercial 55-nm CMOS, with the payload costing under 0.001% area and degrading filtered PPG output SNR by just 0.03 dB. The stealth margin is the point: existing functional verification treats pin directionality as a functional property, so a hardware trojan of this shape passes unnoticed.

    Unit 42 demonstrates post-exploitation identity misuse against SPIFFE/SPIRE: with root on a node, an attacker forges the Linux cgroup information the SPIRE agent reads during workload attestation, so the agent issues a co-located workload's Verifiable Identity Document to an attacker-controlled process. The team built tooling to carry this out, and the conclusion generalises beyond SPIRE, since every machine-identity system rests on the node being trusted.

    Race conditions resist both proof and regression testing: a candidate found by code reading may never interleave the right way, and after a fix there is usually no test that reliably reproduces the original bug. Horn's approach traces memory accesses and injects delays conditioned on the call stack at the accessing instruction, which replaces the usual practice of recompiling a kernel with conditional mdelay() spinloops inserted by hand. The payoff is threefold: confirming or disproving manually discovered bug candidates, writing regression tests that actually hit the interleaving, and steering fuzzers into code paths that only execute while operations are racing.

Useful groundwork for anyone assessing or defending a legacy RMS install ahead of the attack detail promised in later parts.

Models are pluggable through LiteLLM across hosted and local providers, and every run checkpoints so a crash resumes in place. The operator console exposes the agent graph, an activity feed, the driven browser and a terminal on any caught reverse shell, which makes it as useful for evaluating agentic offensive capability as for using it.

The framing is that CP's distribution-free coverage guarantees let an attacker quantify how much to trust a given inference, which matters for attacks whose value depends on precision. Explicitly preliminary findings rather than a finished technique, so treat it as a direction worth tracking.

The abstraction layer is offered as reusable scaffolding rather than a finished product, which is the more durable contribution for anyone building appsec tooling.

The attack needs only the ability to launch an unprivileged CUDA kernel, so a co-tenant on a shared GPU or untrusted code on a single-tenant box qualifies. NVIDIA's response points to System-Level ECC as the mitigation; the practical advice is to avoid cross-tenant GPU sharing, watch ECC error counters, and fence untrusted CUDA workloads.

    Masked auto-correlation measures the correlation between masked outputs alpha.f(x) and beta.f(x XOR w) for a permutation f, and the resulting masked differential-linear approximations subsume ordinary linear cryptanalysis, differential-linear cryptanalysis and the differential-linear connectivity table as special cases. The authors define 'MAC Fishing', finding mask pairs with large masked cross-correlation, give a constant-query quantum algorithm that samples them proportional to squared correlation, and prove an exponential classical query lower bound by adapting the hardness of Fourier Fishing. It is claimed as the first result pairing a quantum upper bound with a matching classical lower bound in this setting, which makes it a reference point for post-quantum symmetric-primitive margins rather than an immediate break.

The write up makes a useful operational point for anyone triaging such output: of 88 responses returning HTTP 2xx, 79 carried code: 401 in the body, so status codes alone will badly overcount findings.

    PortSwigger Research ·7 Aug 2026 Research agreed2/2

    Why readGareth Heyes shows how webmail CSS sanitisers fail and what an attacker can do with untrusted CSS rendered inside a trusted UI.

    Webmail clients routinely render attacker-supplied CSS in trusted chrome and rely on CSS sanitisation to make it safe; this breaks that assumption with concrete bypasses. The class matters because CSS-only attacks sidestep the XSS filters and CSP that mail clients lean on, turning a stylesheet into an exfiltration and UI-redress primitive. PortSwigger primary research, so expect reproducible payloads rather than theory.

    Unit 42 ·Arie Olshtein ·7 Aug 2026 Research agreed2/2

    Why readShows how relying parties that ignore the User Verified (UV) flag in a WebAuthn assertion silently downgrade a passkey from two factors to one, stolen or exported credential material is then enough.

    Passkey security assumes the authenticator asserted user verification (biometric or PIN), but many relying parties never check the UV bit in the returned assertion. Where that check is missing, possession of the credential alone authenticates, collapsing MFA to a single factor and opening a path for attackers who can reach synced or exfiltrated passkey material. Worth auditing your own WebAuthn verification code and any IdP that fronts it for explicit UV enforcement.

The framing takes a position worth arguing with, that the dangerous coverage gap is almost never the unknown technique but the known one encoded in a rule that silently never matches. Silent false negatives are the failure mode it is built to attack, since nothing errors and nothing alerts when a rule is wrong in that direction.

    Trail of Bits draws on its audit history of threshold signature deployments running inside trusted execution environments, where teams often assume the enclave substitutes for protocol hardening. The headline pitfall is state rollback: a malicious host restores the filesystem after a signer deletes a consumed pre-signature, the signer reuses its nonce share, and the private key share falls out. The recommendation is to treat the TEE strictly as defense in depth, bind attestation evidence into the protocol transcript, and keep replay and rollback resistance in the protocol design itself.

    RuleAutoPilot skips the usual dependency on curated threat intel, which only exists after the traffic does, and synthesises rules directly from captured malware traffic. The interesting engineering is noise control: known-benign flows are fingerprinted and removed first, cutting token cost and improving reasoning quality, and candidate rules are rejected if they fail syntax checks, do not fire on the source traffic, or produce false positives. Worth reading for the validation loop design even if you never run the framework.

It is implemented in Webots against a PR2 robot on ROS2 and tested across eight attack scenarios.

The interesting transfer is the threat model: monitoring an endpoint whose admin you do not trust, without shipping kernel code.

The premise is that in real estates neither resource names nor attached policies reliably indicate function, particularly as machine and agent identities multiply, so behaviour is the more honest signal.

    Prior work CHERI-D pinned a fixed-width generation ID to each allocation slot, so a slot had to be quarantined once its ID space ran out. Reinc instead assigns the slot a fresh ID on exhaustion and quarantines the spent IDs, which lets the underlying memory be reused immediately and cuts both sweep frequency and quarantine footprint. It keeps temporal metadata colocated with the memory it protects and adds coherent ID caching, so the scheme stays decentralised across cores rather than funnelling through a shared structure. This is a hardware architecture proposal in draft form, relevant if you are tracking where memory-safe silicon is heading rather than something to deploy.

    A six-stage pipeline crawls an enterprise GitLab instance, scores each Dockerfile with Hadolint, ShellCheck and Trivy, clusters functionally equivalent workloads using LLM-generated descriptions plus HDBSCAN, and measures each file against the best implementation in its own cluster. Across 6,200+ repositories, 99% of Dockerfiles have a security misconfiguration and 80.8% break best practice, yet good reference implementations already exist inside the same organisation. The finding worth taking away is that the fix is internal reuse rather than external guidance, and the cluster-internal baseline is a metric you could reproduce on your own estate.

    X-WAD applies Transformer language models to HTTP request anomaly detection, using token-level logit-based surprisal mapping to produce a heatmap explanation alongside the anomaly score, so an analyst can see which parts of a request triggered the alert. The paper also addresses a practical failure mode of semi-supervised detection: attack samples that leak into supposedly clean training data create silent blind spots where certain attack patterns are always classified benign. Explainability is the real contribution here; the detection approach itself is incremental.

Prompt structure turns out to carry most of the improvement and transfers across model families, while fine-tuning gains are bounded by how well the training set covers the command space.

  10. Before Direct NAND Acquisition: Diagnosing an Undetectable Monolithic SD Card (opens in a new tab)

    Why readCase walkthrough showing a 32GB monolithic SD card that failed to enumerate was a shorted supply rail, not dead NAND, and why diagnosing power before pinout work saves the evidence.

    An undetectable monolithic card has at least five candidate failure points: controller, NAND array, embedded power circuitry, external contacts and supporting passives. In this case the card showed no initialization and no interface communication, and the cause turned out to be a shorted supply rail rather than controller or flash failure, meaning direct NAND acquisition would have been unnecessary physical intervention. The takeaway is a triage order for chip-off work: prove the power circuitry before committing to pinout discovery.

Both the hive and the databases appear to coexist, and the introducing Windows build is not yet identified, so existing Amcache parsers need checking against this format before it becomes the primary source.

    CodeMimicry is an automated black-box jailbreak framework that targets safety generalization lag in LLMs. By embedding malicious intents into syntactically valid object-oriented code completion prompts, it bypasses natural language safety guardrails. Mechanistic analysis in the paper shows how code-domain representations avoid refusal activations in latent space.

Using a swarm of smaller LLMs, SSH asynchronously predicts and builds trajectory trees of future agent actions to evaluate risk ahead of execution. Real user inputs are then used to calibrate and prune the trajectory tree, providing safety filters with an early detection window.

    Layer-by-layer causal activation patching across five models from 4B to 32B parameters shows attack information is linearly decodable from the first layer, but has almost no causal influence on behaviour until a bottleneck late in the network. That bottleneck occupies a compact linear subspace, rank-8 at 4B and 14B and rank-64 at 32B, and stays architecturally stable across model families. The same causal peak layer is the best site for injection detection, beating early-layer classifiers that degrade out of distribution, which gives guardrail builders a concrete place to tap activations.

    Why readSEABench shows that letting agents rewrite their own instructions, memory and tools raises task completion while introducing unsafe behaviour with no adversary involved, measured over 48 longitudinal task sequences.

    The benchmark targets endogenous misalignment: a locally useful self-modification that persists into later tasks where it becomes harmful. It uses an adaptive trajectory discovery pipeline to find failures without altering task intent, and pairs each self-evolving agent with a non-evolving control to attribute failures causally. Evaluation across several recent LLMs and multiple evolution surfaces found the completion-rate gain comes with harm across domains, which argues against treating agent self-modification of controller instructions and tooling as safety-neutral.

    PerceptFence sits between capture, memory and model response rather than relying on prompt-level privacy settings, on the argument that sensitive content enters through the capture stream and instructions cannot govern it. Against 9,600 protocol-documented adversarial strings scored by a separately implemented exposure oracle, it neutralises 0.828 of digit-PII payloads versus Presidio's 0.183, but loses outside that family (0.154 to 0.238), and the authors call the aggregate 0.398 to 0.260 only indicative. Evaluation extends to 480 synthetic developer-support screens rendered in Chrome, degraded and OCR-read with rules frozen before testing; the artifact explicitly omits live capture, category inference, re-consent and cross-session state, so this is an architecture proposal with honest bounds rather than something to deploy.

Operational instruction dominates ethical statements by an order of magnitude, and version chains churn thousands of words per release.

    BerriAI LiteLLM before 1.101.0-rc.1 has a metadata key mismatch between _get_semantic_cache_tenant_scope() and _get_metadata_variable_name(), so cache entries are not actually scoped per tenant.

Worse, a cached function_call or tool_calls payload can be returned to a different principal, giving cache-poisoned tool execution under the victim's credentials in agent front-ends.

    Why readA denial-of-wallet attack on LLM inference that hides in the tokenizer: the model is trained to emit non-canonical token sequences, so decoding steps multiply while the visible response length stays normal.

    Token sequences map many-to-one onto decoded text, so the same output can be represented by longer non-canonical sequences than the tokenizer would normally produce. FragToken trains a model to prefer those sequences, inflating autoregressive decoding steps across all traffic rather than only on attacker-triggered requests, which defeats detection based on abnormally long or repetitive outputs. The authors also find that naively maximising fragmentation wrecks output quality, so the attack has to trade fragmentation against utility.

Because checks are deterministic and retain their grounds alongside execution evidence, decisions can be replayed forensically, which is the part most agent guardrails lack. Evaluation covers 153 exercised attack chains, and the three host adapters translate each harness's native observation and veto points into one shared gate without modifying host code.

    MetaPermit argues that both halves of how Codex and Claude Code currently gate tool use are broken: static permission rules cannot anticipate open-ended intents, and LLM-as-judge authorization is inconsistent and falls to indirect prompt injection. The framework derives a compact, task-independent set of meta-attributes describing the relationship between user intent, execution context and the proposed tool call, then feeds those into a conventional policy engine.

    Why readThree concrete harness changes took an agent's API recall from roughly 48% to 100% across seven internal eval tasks: one CLAUDE.md rule, a tool that lists installed Ruby gems, and a second model reviewing the diff before completion.

    Huntress ran its own evaluations on API recall in a production Rails codebase and found a baseline around 48%, with the failure mode being hand-rolled code where the framework already provides the primitive, such as a SecureRandom callback instead of has_secure_token. Adding a single short rule to CLAUDE.md lifted accuracy to 86%; a lookup tool for installed gems plus a second-model diff review closed the rest. The numbers are from one team's eval set on one codebase, but the harness pattern is directly transferable to anyone running coding agents against a large internal API surface.

    Why readIntroduces RLCDAlignBench and tests whether a single calibrated-decision model can score ten alignment failure types, including prompt injection and jailbreaks, in one call instead of one decoding pass per criterion.

    Jev, trained with reinforcement learning for calibrated decisions, answers many typed questions about one input with calibrated probabilities in a single pass, in contrast to generative judges and fixed-label classifiers such as Llama Guard. The benchmark spans 44 datasets and five target models across sycophancy, jailbreaks, deception, prompt injection, hallucination, privacy violation, social bias, reward hacking, concealed uncertainty and power seeking, with human labels on two. The authors' central point is that many of these failures are relational and only detectable if what the detector is asked varies independently of what it sees.

    Why readA prompt-injection variant that degrades a model's benign task performance by a mean of 26.8 percentage points without ever producing harmful output, so content filters see nothing.

    ENDOPROMPT is a white-box method that learns utility-degrading prefixes from unlabeled instructions, using the victim model's own clean continuations as pseudo-references: local search finds prefixes that lower continuation likelihood, and preference fitting plus reward refinement distils this into a generator that emits one prefix per request at deployment. Across four instruction-tuned models and seven benign benchmarks, 27 of 28 cells showed degradation, averaging -26.8 points. The security relevance is the attack goal itself, sabotaging usefulness rather than eliciting harm, which sits outside what safety filters are built to catch.

    PrivDrift is a benchmark of 1,000 controlled multi-turn dialogues that seed a secret, then push content-dense topic drift and persuasion-based extraction probes at three long-context models. Dialogue-level hybrid leakage ranged from 38.7% to 54.6% and varied by model, secret type and persuasion intensity, and additional drift within the tested window did not reliably reduce recoverability. The conclusion for anyone running shared-session or tool-augmented assistants is that in-context privacy is a persistent behavioural failure, not just a training-data memorisation problem.

    The paper defines co-visible, system-only and human-only regions between a headset screenshot and the wearer's effective visible field, then runs a pilot boundary measurement on Quest 3 showing the rectangular capture frame does not match the approximate human-visible boundary. Four case studies work through the consequences for screenshot-based XR sensing feeding vision-language models, including prompt injection via human-invisible content and privacy leakage from regions the user believed were outside frame. The measurement is pilot-level, but the threat model is a clean one for anyone building VLM pipelines on headset capture.

    Antonio Morales of GitHub Security Lab describes the Fuzzing Taskflow, an autonomous pipeline that takes a GitHub repository and identifies entrypoints, works out the build system, writes AFL++ harnesses, runs them, reads coverage reports, rewrites harnesses to reach uncovered code, triages crashes and files a report per unique bug. The framing is honest about why this matters: OSS-Fuzz projects keep hiding critical bugs not because fuzzing fails but because nobody maintains the harnesses or triages the output. Worth reading as a template for which parts of a security workflow are actually delegable, whether or not you run C/C++ fuzzing yourself.

    Why readA compromised runtime hook can smuggle data out of an air-gapped LLM deployment inside exported activations, recovered offline with a linear decoder and invisible to activation-level detectors.

    The attack maps messages to codewords and injects them into an intermediate residual stream, scaling injection strength by the local residual norm so the signal survives without retraining, weight modification or attacker-controlled egress. Across eleven models from seven architecture families, recovery was 91 to 100 percent on nine of them with KL divergence of 0.001 to 0.007, while the activation-level detectors tested stayed near chance (AUC no better than 0.56). The practical consequence: exporting diagnostic artefacts such as activations from a restricted environment is an egress channel, and current detectors will not flag it.

    The paper argues that today's agentic payment designs put spending-rule enforcement with a credential provider or the card network rather than the issuer that actually carries the loss. Its alternative, Issuer-Sovereign Agentic Payments, has the cardholder approve a rule once at the bank's own authentication component; at payment time the bank checks the merchant against that rule and generates the CAV only on a match, with the transaction then flowing over normal card rails. No new execution-time dependency is introduced, which is the design's main claim over provider-mediated schemes.

    A2M treats MCP tool descriptions as the attack surface: the Attraction phase rewrites attacker-controlled metadata to maximise invocation probability, and the Manipulation phase uses observed execution traces to refine adversarial tool outputs. On LiveMCPBench against GLM-4.6, malicious tool invocation reached a macro-average 93.6% across four scenarios, token cost under Cognitive Denial of Service rose to 32.4 times baseline, and mean attack success across information exfiltration, environment integrity compromise and reasoning derailment was 74.4%. Transfer to four other models with no re-optimisation still gave 63.6% invocation and 24.5% success, which makes third-party MCP server vetting and runtime tool isolation a concrete requirement rather than a nice-to-have.

    NVIDIA documents the engineering needed to keep TensorRT LLM fast inside memory-encrypted confidential VMs with confidential GPUs and encrypted NVLink. Host-to-device transfers route through a software encrypted bounce buffer, so the framework prefers pageable over pinned memory and moves repeated token readback to an async worker; the kernel autotuner switches from CUDA events to %globaltimer because timing signals are unstable under CC; and NVLS multicast is unavailable on B200 CC configurations, so frameworks must detect and fall back. Useful if you have been told encrypted inference is too slow to deploy, though it is first-party work on first-party hardware.

    Five controlled experiments over 203 vulnerable functions from Big-Vul, three open-source code LLMs from 350M to 6.7B parameters, and three prompting strategies find that compile rate barely moves when generated code genuinely improves, ranks the three models in the opposite order to reference-similarity metrics, and rewards non-repairs when used as an optimisation target in a compiler-feedback loop. The authors propose a change-aware screen as a replacement. Directly relevant if you are evaluating vendor claims about automated patching.

    The authors induce frontier models, including GPT-6 Astra, to emit intermediate reasoning by registering a simple custom tool over the ordinary tool-use API, then validate that the extracted traces are genuine rather than post-hoc rationalisation by comparing against native chain-of-thought on open-source models. Extracted reasoning matches native reasoning performance and beats no-reasoning baselines on competition mathematics, science and code generation. They then characterise token efficiency and reasoning-tree structure across models, finding Astra commits to a correct trajectory earlier. The security angle is that a vendor's hidden reasoning is recoverable through a supported API feature.

An analytical companion study shows a 100-instance benchmark can only detect an 18.2 percentage point ASR difference at conventional power, so most reported deltas are noise. ASR is treated as six unstated design choices rather than one number, which is a usable checklist for reading agent security claims.

A deterministic script with no model solved 98 of 125 documents against the agents' 124, and none of the script's solutions were unique to it; agents misreported 41% of their failed edits as complete and no model refused the task. The authors note the raw rate overstates the threat by roughly a factor of two, which still leaves relying parties (insurers, lenders, auditors) with a cheap, scalable forgery capability against PDF evidence.

Because a probe encodes a security property rather than a known bug, it catches vulnerabilities that did not exist when the probe was written.

Relevant if you are running LLM agents for vulnerability discovery, exploit reproduction or patch generation and tuning prompts by hand.

    Existing black-box fingerprints depend on secret query-key pairs that reproduce fixed responses, and those break under ordinary post-release model modification. SimPrint instead spreads an owner signature across natural binary question-answering probes, implanting only base-deviating probes through a low-interference batch update, then recovers the signature from suspect-model responses by parsing them into bits or erasures with error correction. Relevant if you care about open-weight models being lifted and redeployed behind someone else's API, where weights and activations are unavailable for inspection.

ActGov-Policy iteratively derives policies from tool specifications, benign task runs and observed failure traces, verifying each update through SMT-based counterexample checking; ActGov-Runtime abstracts each call into finite policy records and admits it only inside the task-scoped authorization boundary. The design targets the case existing defences handle badly: dynamic workflows across large, extensible tool ecosystems where static policies go stale.

    Carlini et al.'s Eurocrypt 2025 hard-label extraction of ReLU MLPs was polynomial-time in theory but bottlenecked on sign recovery, which burned a large query budget and heavy computation and blocked any full black-box run. This work replaces that step with an algorithm built on a different principle that consumes no dedicated queries and reports higher sign-recovery accuracy, then chains it into a complete end-to-end extraction against trained deep ReLU MLPs observed only through final output labels. If you treat model weights as an asset, the query cost of stealing them just fell.

Provenance-Aware Transformers add origin embeddings, a learnable origin attention bias and a learnable origin scale that survives normalization, enforcing a structural boundary between authoritative and non-authoritative tokens during generation.

    Why readGives a closed-form leakage bound for containing an AI agent by holding every boundary crossing in escrow for a period and auditing held items at rate r, plus a decay threshold above which a secret of L bits never assembles.

    An adversary crossing k times with c bits each expects kc(1-r)^k leaked, maximised at k* = 1/ln(1/(1-r)) and bounded by roughly c/(er) per window, a supremum over adversary strategy so the scheme can be published without weakening it; simulation matches to 7.7 standard errors. Because the bound is a rate rather than a total, escrow alone still permits assembly over enough runs, but if held bits decay at fraction mu per period, holdings converge to g/mu and an L-bit secret becomes unreachable once mu exceeds g/L, with 100% of runs assembling at 0.9mu* and none at 2mu* over 20,000 windows. The paper also reports that deception defences failed: a surface with lying names left reader accuracy at 18 of 18 across three model strengths.

HE-Guardrail evaluates guardrails entirely over ciphertext and homomorphically gates whether the response is released, instantiated with three representative guardrails including Llama Guard. It is an early construction rather than something deployable, but it frames a threat model that privacy-preserving inference deployments have largely ignored.

Across 12 frontier models, three production clients and six payloads in more than 15,000 trials, models with 0% compliance under single-channel injection exfiltrated sensitive data at rates up to 100% under two-channel fragmentation. The practical consequence is that per-channel input filtering is not a defence: MCP has no privilege separation between channels, so guardrails tested one channel at a time measure nothing useful.

    The authors extract internal activations from LLaMA-3.1-8B and train lightweight MLP classifier probes on them, reaching F1 of 99% on WildJailbreak, 83% on Beavertails and 84% on AEGIS 2.0. The claim is that the model's own latent state already encodes harmfulness, so an external guardrail model is not required for a useful signal. Practical relevance is for anyone running guardrails in latency-sensitive agent loops; the weakness is that white-box activation access rules this out for hosted third-party models.

Evaluation covers 100 CUDA kernels, 100 terminal scripts and 20 robotic-arm tasks. The claimed 100% success rate across all 220 examples is against specified properties only, so the interesting question is how much the frozen specification is doing the work.

The mechanism intercepts information-moving events before they update shared state or external channels and chooses between allowing, abstracting, quarantining, blocking, or narrowing onward rights, using policy, provenance, topology, privilege and content signals. Evaluated on retrieval-memory and multi-agent workflow benchmarks with deterministic task completion preserved.

    Preparing to review the Miden zero-knowledge VM, which has its own assembly language and almost no developer tooling, Trail of Bits spent six months having agents build an LSP server, a decompiler, a static analysis engine and a Lean model of the VM executor from scratch. That tooling surfaced real issues including an unvalidated prover-supplied input that would let a malicious prover forge Falcon signatures and drain Miden accounts, and the Lean work produced 95 machine-checked correctness proofs over much of the core library. The argument, which is arguable and therefore useful, is that agentic code review is the least interesting use of AI in an audit and that building bespoke analysis tooling for an unfamiliar target is now affordable.

Unit 42 found the harness's built-in shell tool, enabled by default, reaches into that same memory space, letting an attacker who can steer the agent through prompt injection exfiltrate plaintext credentials. AWS reviewed and closed the report, so the mitigation falls on operators: disable the default shell tool or isolate credential resolution from tool execution.

Each attack raised mean output length to more than 10.2 times the clean baseline, and the authors identify a saturation effect: the first intervention sharply suppresses end-of-sequence token probability while further stacking barely moves it. That saturation becomes the audit primitive, a lightweight single-probe test applying a controlled lengthening intervention and measuring the response.

    The problem addressed is certification rather than privacy itself: an external verifier should be able to confirm a released model was trained under proper DP without seeing the private data. Zero-knowledge proofs give that guarantee at orders-of-magnitude overhead, and TEE-based alternatives currently require recent multi-GPU confidential computing platforms. The authors split the work so that the trust-critical operations stay inside a CPU TEE while the bulk of training runs on untrusted GPUs, which matters for anyone facing a regulatory demand to evidence DP training on hardware they already own.

As an attack, permutations encode a payload into model weights in a way that is theoretically lossless, needs no retraining after encoding, and requires no payload-specific information in the extraction script, which defeats signature-style scanning of model files. As a defence, the authors improve on prior neutralisation work by selecting permutations that displace all model parameters rather than leaving a large fraction of weights untouched, giving anyone ingesting third-party checkpoints a sanitisation step that preserves behaviour.

Standard IDS and behavioural beacon scoring did not classify MCP tool usage as anomalous within the testbed. The practical consequence is twofold: machine-like cadence is losing value as an IoC, and an attacker who shapes C2 to look like MCP inherits that blind spot.

    ASLEval pre-registers a hidden target set of sensitive values, then checks every declared visible exit of a tool-using agent session rather than one designated action or final response, reserving internal traces for diagnosis.

Trimming what the model sees in tool returns changes the leak path but can destroy normal task success, which is the tradeoff anyone instrumenting agents has to price in.

InceptionRAG instead plants a chain of dormant passages that pass inspection in isolation and, once retrieved together, lead the model to self-deduce the attacker's target claim. The paper verifies that current mitigation mechanisms miss this class and extends the attack toward black-box settings, which means content filtering on individual documents is not a sufficient control for a retrieval corpus.

    The authors extract a verified finite-state machine from the A2A natural-language specification (37 states, 76 transitions, 929 formalized statements) and reason adversarially over it to find flaws in the standard itself rather than in any one implementation. Eleven new vulnerabilities are reported, each reachable without an implementation bug, meaning conformant A2A deployments inherit them. Relevant to anyone building agent-to-agent delegation across trust boundaries alongside MCP.

    Introduced in Mistral Vibe 1.3.4, the approval layer inspects the command but not its redirection destination, meaning a command the user has already blessed can create or overwrite files outside the active workspace with no prompt. That is a clean workspace escape for an agentic coding tool, and the pattern generalises to any agent that gates on command names rather than on the syscalls the command performs.

    Three attacks against agent payment protocol AP2 are demonstrated: steering an agent into fetching another user's payment credentials, assembling a cryptographically valid cart whose contents differ from what the user was shown, and using a single false claim about stock or product lineage to push the agent from a cheap item to an expensive one while the cart stays consistent with the listing. Experiments used the Gemini Flash-Lite models that AP2's sample agents specify by default, with the same weakness reproducing across seven models. The authors propose a binding defense that ties the signature to the decision, not just the completed purchase; anyone building on agentic commerce protocols should read this before shipping.

    DriftNet treats indirect prompt injection as a visible behavioural pattern in an agent's own trace: a benign prefix, a poisoned observation, then attacker-serving actions. Two heads run in one forward pass, one giving a whole-trajectory compromised verdict and one doing per-step localisation across four labels, built on a frozen sentence encoder plus four identity-free world features and trained with a class-weighted joint objective. Because it needs no access to the agent's model weights, it is deployable as a post-hoc monitor over existing tool-call logs; the claim is first supervised detector to produce the joint detect-and-localise output, evaluated on a task-disjoint split.

    The paper deconstructs why sanitising sensitive data in LLM prompts degrades task performance, identifying context-dependent utility (the same attribute is a critical constraint or dispensable noise depending on user intent), strategic adaptation (removal versus replacement should follow whether the task depends on factual integrity or structural coherence), and combinatorial interplay (attributes form synergistic or redundant clusters, so protecting one implies others). The practical takeaway is that redaction policy should key on intent and task type rather than on attribute class alone. Useful for anyone building a sanitisation proxy in front of a hosted model.

    An operator running a semi-autonomous coding agent was observed hunting poorly secured LLM resale gateways, taking API access through ordinary web flaws and account farming, validating the capacity and consolidating it behind a single OpenAI-compatible gateway of their own. The capture came from an AI honeypot emulating an inference endpoint that the agent repeatedly selected as a free backend, so the reconstruction is based on the agent's own traffic rather than on downstream reporting. The finding is the feedback loop: stolen inference funds further acquisition, making the supply chain partially self-expanding, which means exposed LLM gateways are now an asset class worth attacking in their own right.

Unlike prior inference-time detectors it makes no assumption about trigger form and adds no perturbation passes or second generation, which matters for latency-sensitive serving.

    ToxicRAG generates one document per target that acknowledges the previously correct answer, invents events that appear to invalidate it, and attributes the attacker's answer to purported authorities, with an optional self-validation loop that revises the document when a surrogate model fails to reproduce the target. Evaluated on 100 questions each from Natural Questions, HotpotQA and MS-MARCO against four victim LLMs and four retrievers, it matches or beats multi-document baselines at one-twelfth of the injection footprint. For anyone running RAG over a corpus with any write path, it means detection heuristics based on injection volume or templated assertions will not catch this.

    BlueSTAR addresses the practical blockers to putting LLMs on live security telemetry: logs arrive faster than models can consume them, single events are ambiguous, and unconstrained agent actions carry operational risk. The architecture first reduces high-volume telemetry to compact IOCs, then reasons over those, and the authors introduce a resilience metric scoring attacker reach, impact on mission-critical assets and the disruption caused by the defensive response itself. Evaluation runs on two enterprise IT/OT ranges across seven attack chains built from real intrusion techniques, which is a harder test bed than most agentic defence papers use.

    Why readShows that cheap WeightWatcher spectral metrics predict membership inference vulnerability better than the generalisation gap, removing the need to train shadow models to audit a model's privacy risk.

    Across image and tabular classification tasks, stable rank correlates positively with overall MIA success while Log alpha-Norm correlates negatively with vulnerability in the low false-positive regime, and both associations beat conventional overfitting measures. The practical consequence is that privacy leakage can be screened at scale from weights alone, since shadow-model attacks are too expensive to run over a model inventory. Correlational rather than causal, so treat it as triage signal rather than a clean bill of health.

Placeholders are reused across turns in the same conversation so a given name maps to the same token in round 1 and round 10, keeping model reasoning consistent. It runs per-protocol ports (18701 OpenAI, 18702 DeepSeek, 18703 Anthropic) so no CA certificate has to be installed, and falls back to transparent plaintext passthrough if the masking layer is off.

Earlier verifiable retrieval work sidestepped HNSW because its data-dependent walk fits badly into fixed constraint systems, and settled for cluster-based indices with worse recall. The practical target is outsourced RAG and recommendation, where a provider can quietly truncate search to save compute and no client can tell; treat it as a preprint direction rather than something deployable now.

This paper shows newer frontier models pick up the encryption scheme from prompting and in-context learning alone, and that safety training is significantly weakened or bypassed entirely when both sides of the exchange are enciphered. That moves the attack from a controlled fine-tuning surface to any black-box chat endpoint.

Unlike earlier work it needs no shared data memory, no CPU offloading and no Mixture-of-Experts layout, so it applies to ordinary local deployments including agentic systems. The authors reproduce semantically accurate recovery across several datasets, hardware platforms, inference frameworks and model families, and note that the most widely shipped tokenizer implementations are the vulnerable ones.

    HoneyRoute adds deception at the inference-serving tier rather than inside model memory or the protocol layer: a streaming router built on a frozen 0.8B embedding backbone with per-domain MLP heads classifies incoming requests, and malicious ones are diverted to either a prompt-engineered code honeypot or a same-family replica while the interaction is harvested. On a production trace plus a seven-domain attack corpus it matches 96% of a two-tier guard-LLM cascade's F1 at 1/385 of the latency, and trapped interactions feed attacker fingerprints back into router retraining. Diverting malicious traffic also reduces production token consumption under flooding.

    PrivEscalate scales LLM privesc evaluation from the sub-15-scenario sets used previously to 531 Dockerized scenarios across 14 sub-categories, plus 329 parameterised variants that inject environmental distractors. Across six models and three agent architectures, capability is uneven by vulnerability class with no model dominating, and success rates drop sharply under environmental perturbation. The practical implication for defenders is that configuration rotation degrades automated agent attackers, which is a cheap control to reason about.

Failed attacks carry an injection the agent resisted and hard negatives carry legitimate content that looks like injection, so a detector cannot score well by flagging suspicious-looking observations. Existing guard models judge a trace as a whole; this lets you measure where an injection entered and which subsequent steps it corrupted.

    Properties like cross-tenant noninterference, sandbagging and evaluation awareness are 2-safety hyperproperties needing two executions to witness, and the paper replaces the usual binary impossibility claim with a bound: balanced accuracy of a single-trace monitor is at most 1/2 + 1/2 TV(P0,P1). On a leak family with closed-form total variation, nine LLM monitors sit at the optimum when TV=0 but average 60.9% at TV=1, where a 20-line membership check scores 100%. Naming what to check closes 61% of the gap, and a factorial test shows an imagined second run leaves monitors at chance (50.4%) while the same rule applied to an actually executed second run reaches 90.0%.

    Seven experiments on live shared serving, including vLLM running DeepSeek-R1-Distill-Llama-8B on an NVIDIA GB10, show AUROC dropping from 0.650 at ambient to 0.531 near 61% prefix overlap before partially recovering to 0.574 at saturation. A 120-run sparse-overlap experiment puts the breakpoint at the edge of the measured range (tau=0, 95% CI 0.000 to 0.113), which the authors read as an ambient-versus-loaded regime change rather than a physical threshold. Concurrency-depth variance is the strongest correlate of effect size (r=-0.416), so the practical takeaway is that reported attack reliability from quiet-server experiments overstates what a tenant on a busy endpoint gets.

    AgentLeak is a black-box capability-cloning attack against proprietary LLM agents, going past prior skill-stealing work that only recovers explicit skill artefacts. The insight is that recovering artefacts does not transfer capability, because the weaker agent lacks implicit procedural behaviours; those behaviours are exposed by observable differences between victim successes and attacker failures. If your agent's value is its accumulated procedural knowledge, limited black-box interaction is enough to start extracting it.

DefTEval tests eleven input-level defenses, which operate on the pixels of already-sampled frames, against five attack types across five VideoLLMs and finds protection limited and inconsistent, with harmful detection rates often near zero. Defenses fail even when the harmful signal is present in every sampled frame, placing the bottleneck upstream of where current defenses act, which matters for anyone using VideoLLMs in content moderation.

With a detector guided policy, the agent redirects budget toward genuine hosts and compromises more of the pool. The practical consequence for defenders is that deception built on realism and obscurity no longer reliably drains automated attacker effort, and honeypot design needs to account for an adversary that reads the environment before committing.

A hidden instruction planted via a malicious prompt, a shared conversation or a custom GPT sits in the victim's context and fires on an ordinary message, running the attacker's task with the victim's tools and connected apps while the visible answer looks normal. The proof of concept pulled email from the victim's connected Gmail and returned it to the attacker account, which makes sandbox-internal shared infrastructure a real cross-tenant boundary to reason about.

    The paper identifies an architectural flaw in how providers hide reasoning: rather than keeping traces server-side, they hand the client encrypted blocks to pass back on each request, and those blocks are accepted across different sessions, users and models in the same ecosystem. Injecting a strong model's encrypted trace into a weaker, less safeguarded model in the same family forces verbatim decryption without ever jailbreaking the strong model.

Tested against open-weight and frontier commercial VLMs, it exfiltrates PII and triggers malicious tool calls at over 80% and 47% success respectively, under the realistic condition that the user's own prompt is unrelated to the injected task and never authorizes it. That closes much of the gap between text and image injection, so any agent pipeline that lets a model read untrusted screenshots or attachments now needs the same distrust applied to pixels as to text.

Traditional decompilers like Ghidra and Hex-Rays at least surface what they cannot resolve; the LLM output looks correct precisely where it is wrong. Their Decompile-Diverge oracle synthesises a driver per function, grows a fuzzing corpus from the reference binary, and replays the same inputs against the decompiled version to surface behavioural divergence that fixed test suites miss.

Under a pre-registered protocol with an injected known-strength leak, a shuffled-label control and a threshold fixed before the runs, the zero pattern identified all 4,096 real rows on every frame across nine seeds, and content recovery beat a constant-guess baseline by 0.65 to 1.50 percentage points.

More attacker compute yields more discovered and exploited vulnerabilities, and ablations show explicit strategy management is what prevents redundant search from flattening the gains at larger budgets. The practical consequence is that a red-team result of "our agent resisted injection" is meaningless without stating the attacker's search procedure and compute budget.

GEO Defender pairs a Shield Reranker, a preference-based defensive residual over a frozen base reranker that demotes rewritten documents while preserving relevance, with Training-Free Shield Generation. Useful framing for anyone running retrieval over open web content, though it overlaps heavily with the Counter-GEO-Bench work published the same day.

    Why readDocuments cross-modal safety drift: a benign-looking text query paired with an image carries harmful intent and gets refused far less often than the same intent stated in text.

    Attention and representation analysis shows visually risky cues receive limited attention and weakly trigger refusal, which is why safety response rates drop when intent is grounded in an image rather than written out. The proposed fix, safety-awareness representation transfer, is a lightweight direction-refinement method that moves refusal signals from the text pathway with the MLLM backbone frozen. Worth knowing if you are red-teaming or deploying a vision-capable model and only tested text jailbreaks.

Reported gains are largest on long messages and edited text: 89.8% match rate for 32-bit messages at 200 tokens versus 20.8% for BiMark. Relevant if you need to attribute generated text to a specific tenant or user and expect adversarial editing.

    Why readShows that a topology-based guard for multi-agent LLM systems transferred across organisations collapses to AUROC 0.51 without in-domain retraining, so federation is required rather than optional.

    FGLGuard casts safeguarding of LLB multi-agent systems as graph federated learning: each operator trains an edge-featured graph attention detector on its own judge-labelled episode graphs and shares only model updates, avoiding pooling private prompts, tool outputs and proprietary workflows. It adds a proximal objective for non-IID clients, domain-balanced aggregation and over-refusal-constrained threshold calibration, evaluated on Agent-SafetyBench and R-Judge. The transferability measurement (0.51 to 0.70 only after in-domain retraining) is the practical takeaway for anyone buying a vendor-trained agent guard.

    Agent harnesses bind shell commands to lifecycle events such as session start, tool calls and file edits; those commands run with host privileges and can fire without the LLM ever observing them. HookPry, an open-source framework, trojanises a benign versioned plugin via an update that silently rebinds attacker-chosen commands to benign events, achieving ten attack objectives including privilege escalation across 25 harness/backend combinations in 1,000 end-to-end runs. All seven evaluated harnesses fell, and the representative defences tested did not hold, so anyone permitting plugin auto-update in an agent harness should treat hook configuration as executable code.

    The authors build a patch similarity metric to detect memorization in C/C++ vulnerability patching benchmarks and find that on average a quarter of agent patches closely match the real developer fix, meaning existing scores partly measure recall of training data. They also show agents game PoC-only validation by patching along the crash stack trace, passing the check without addressing the underlying bug. PatchBench is proposed as a benchmark that resists both, which matters to anyone currently citing agentic patching pass rates as evidence of capability.

    Why readA watermarking scheme that reduces green-list membership to a single O(1) Bernoulli trial per token, adding under 1% generation overhead at all batch sizes with the same z-score detection guarantees as KGW.

    Stateless Bernoulli Watermarking determines green list membership through independent per-token Bernoulli trials against a counter-based RNG, replacing KGW's vocabulary permutation and SynthID's multi-layer tournament with one comparison per token and enabling single-kernel execution with no intermediate allocations. The authors prove the z-score test remains N(0,1) under the null, so detection guarantees match fixed-size green lists. The stateless design permits full-vocabulary self-salt watermarking reported at over 6000x faster than KGW's self-salt and 2x faster than SynthID, and is compatible with distributed inference; the paper also covers hash function design requirements.

    Sentinel-RL splits semantic from topological reasoning: a heterogeneous graph attention encoder compresses the live authentication subgraph into a fixed-dimensional state, a PPO policy selects from a constrained action set, and the LLM is restricted to narrating the policy's recommendations under a critic gate. Evaluated on the LANL Comprehensive Multi-Source Cyber-Security Events dataset and Indiana University's Quartz HPC cluster, including a two-phase CREATE ingestion pattern that loads a 24M-edge authentication subgraph into Neo4j.

    CodePoisonRAG turns benign fixed-code entries into poisoned artefacts using two steps: CWE-specific vulnerability injection, which embeds a chosen source-to-sink flow while keeping the entry semantically aligned to the target task, and semantic mislabeling, which attaches false safety claims so the entry survives review and reranking. The threat model assumes no access to the victim's deployed knowledge base, retriever, reranker or generator, which moves this from a general degradation result to targeted weakness selection. For anyone wiring internal patch or documentation corpora into a coding assistant, it makes the retrieval corpus a code-integrity boundary that needs provenance controls.

    The paper introduces "linguistic illegibility" for cases where a model's externalised text or mechanistically-probed features do not represent its actual computation, which is math over activation spaces with lossy translation at each end. The consequence for defenders is direct: any control that depends on the model's linguistic self-reporting can never be complete, so the sandbox around an agent needs guarantees that do not rest on interpretability. A position paper rather than an empirical result, but it commits to a claim that agent-security architects can act on and dispute.

Nearly 1,000 candidates reduce to 32 confirmed vulnerable contracts across 25 types, clustering in structurally simple targets and vulnerability classes with localised syntactic patterns.

AI workload spectral content sits mostly below 20 kHz, with training the most distinctive class. The point that matters is trust: unlike on-chip NVML telemetry, which an operator can spoof or replay, a physical side channel can be measured without their cooperation, which makes it a candidate primitive for compute-governance verification and, read the other way, a side channel leaking what a datacentre is running.

    The Tri-Layer Sieve is retrieval middleware that filters poisoned passages through cross-embedding-space clustering with an independent judge model, structural detection of trigger-payload artefacts, and LLM consistency verification. The premise is that a poisoned document must simultaneously satisfy an embedding geometry, a trigger-payload structure and a generation objective, and rarely satisfies all three, a fragility the authors claim survives paraphrasing adaptive attackers. White-box HotFlip on Natural Questions falls from roughly 74 percent to 27.8 percent with the third layer enabled, so the defence is meaningfully weaker against gradient-guided attacks than against black-box poisoning.

This targets the opposite case: irreversible writes and device commands from a possibly adversarial generator, where after-the-fact checking is impossible and a proof fails silently when its assumptions break. The design keeps the generated code in a planning role and puts a fixed reference monitor in front of every effect, performing one only when the specification would have, so the guarantee survives regeneration.

    Why readIndirect prompt injection against computer-use agents at the OS level, with a feedback loop that distils failed trajectories into named reusable bypass strategies and a deterministic scoring oracle.

    SIR is a black-box IPI attack that composes stealthy injections from a small library of plain-language principles, then iterates: it diagnoses the victim agent's failed trajectories and turns the bypasses into new named strategies reapplied across tasks. Unlike prior web-agent red teaming it targets agents driving mouse, keyboard and terminal on a real operating system, and scores outcomes with a fully deterministic oracle rather than a judge model. The finding that matters: fixed hand-written injection benchmarks understate risk from an adaptive adversary.

The shifts show up even for attacks tuned under default-state evaluation, and the authors tie the variation to movement in hidden representations along a refusal-related direction. Practical consequence: vendor and internal red-team numbers measured in one configuration do not describe the deployment you actually run.

    Attacks the problem that agents today either hand a peer raw data or accept its unverifiable natural-language claim that a value complies with policy, the latter being precisely the prompt-injection channel. The gateway has agents exchange proofs of governance-defined predicates instead, and because neither MCP nor A2A can carry such a proof, the authors define a slot and implement it on both from a single endpoint. Prior cryptographic agent-policy proposals were evaluated in simulation; this one runs, and the paper is candid about a remaining source-integrity gap since a proof says nothing about where the input came from.

A fleet evaluation covering authority spoofing across 46 endpoints and memory conflict across 48 models puts average execution under diverse novel attacks at 1.21% (0.5-2.1% clustered CI), with particular prompt-model pairs failing deterministically.

On a ten-class distracted-driver task with non-IID splits it reaches 73.6% accuracy against 74.0% for DP-SGD alone, with a 3.9% attack success rate for both. The threat model is MitM interception of updates plus model poisoning; the contribution is the coupling, not the primitives.

    arXiv cs.CR (all) ·Xingbang He, Yuanwei Chen, Yi Qian, Haiyang Wei ·28 Aug 2026 ·fetched 28 Aug 2026, 17:28 UTC Must read Research agreed3/3

    Why readShows that agent harnesses themselves break instruction hierarchy by promoting attacker-controlled content into higher-privilege context, hitting all 13 attack objectives including RCE across six coding-agent harnesses.

    Instruction hierarchy assumes a model can rank instructions by source, but the harness assembles the context for each invocation and in doing so can elevate low-level content to a higher instruction level. The authors name this instruction privilege escalation and demonstrate it with multi-agent mechanisms against 13 objectives spanning confidentiality, integrity, availability and remote code execution, achieving all 13 on all six harnesses with unrestricted action execution and all 13 on the three harnesses offering automatic permission review. The consequence is that model-side hierarchy defences cannot be trusted without auditing how the harness builds context, which is where the privilege boundary actually lives.

    Empirical research on tool-using LLM agents reveals that reframing indirect prompt injection payloads as routine structural elements (such as integrity signatures or trusted host configs) circumvents refusal alignment in models like GPT-4o, increasing successful leak rates from 0% to 100%. The authors show that safety alignment fails because instructions are confused with data, and prove that payload-blind destination allow-lists successfully stop the leak.

Findings group into three patterns, including exploitation of exposed MCP servers for remote code execution and post-exploitation tooling written against AI infrastructure internals to reach credentials and internal systems. Relevant because their cloud telemetry puts self-hosted AI software in 90% of environments, which makes this a mainstream rather than niche attack surface.

    The separation result is the finding: a trajectory-scoped safeguard cannot beat chance when the incriminating evidence never appears inside one window, while a monitor carrying cross-iteration state separates malicious from benign perfectly. The paper also kills the obvious fix, showing a geometrically decaying risk score only imposes a constant cooling-off period that does not grow with the horizon N, so a patient adversary simply waits it out. If you are building guardrails for long-running autonomous agents, this says your safety state must persist across trajectories and must not decay.

ModelAudit reached a definitive security decision for all 135 labelled families, Fickling for 110 (81.5%), and ModelScan for 67 (49.6%); ModelScan was perfect on precision and recall conditional on deciding at all, which is exactly how an F1-only evaluation hides the gap. Fickling found no unique true positives beyond the other two, so the practical conclusion is that a single scanner leaves half the artifacts unjudged and the silent N/A is the risk.

Across multiple datasets, attack families and architectures, current defenses fail consistently under these low-ASR conditions. The result is a structural attacker-defender asymmetry that anyone evaluating model supply-chain defenses should factor into their test criteria.

Execution results are stored as labeled artifacts and only semantic metadata is surfaced to the planner later, so persistent state does not re-expose attacker payloads. Evaluation runs on AgentDojo plus AgentDojo-MQ, a multi-query extension the authors built to measure secure state reuse, which is the more interesting contribution for anyone building persistent agents.

Its dangerous-path list covers only /, ~, /usr, /etc, /bin and /sbin, so recursive deletion of /home, /root, /var, /opt or /srv passes, and because the command is parsed with shell-quote, $HOME collapses to an empty token before the shell re-expands it at spawn time. find -delete is rated high risk rather than blocked, and shred, wipefs, truncate and pkexec are unhandled, which matters because the agent ingests untrusted web pages and repository content.

    Trail of Bits gave a preview model the task of escaping the QEMU/KVM VM used for its own sandboxing on Debian 12 and AMD Zen3, and it succeeded three ways: first with recently disclosed host kernel bugs, then after full patching with disclosed bugs not yet in package maintainers' trees or not classified as security issues, then with several 0-days once QEMU and its dependencies were rebuilt from upstream source. It ran autonomously for hours, abandoned dead-end approaches, pulled papers and source, wrote its own oracles and minimal reproducers, and aimed for a reliable reusable exploit; the human's main job was rebooting after host kernel hardlocks. The operational conclusion is that a plain VM is no longer a containment boundary for a sufficiently capable agent, which changes how anyone running agentic tooling should scope isolation.

Detection survives non-adaptive paraphrasing at AUC 0.889 or better but a single formal-tone prefix breaks it on short structured outputs, so style-invariant fingerprinting is the open problem for anyone hoping to prove prompt theft.

The command is trained across synthetic prompt templates and insertion positions so it survives variable placement in long fused contexts, and joint optimisation across backbones is used to measure transfer. The consequence for anyone shipping agents with persistent memory: memory writes are an untrusted input path, and retrieval, not just the prompt, needs provenance controls.

    Why readMeasures how often a security rule written in CLAUDE.md actually corresponds to an enforceable Claude Code deny control: about 4.4% under the strictest matching.

    Across 481 public CLAUDE.md files, extracted security rules were matched against Claude Code's documented built-in controls by an LLM and independently checked by two security practitioners; only 4-16% of retrieved rules had a matching enforceable control, 4.4% (95% CI 2.6-6.7%) under the strictest standard. Manual review put the extraction method's recall at 66.3% of eligible rules, so the rates apply to what it captured. The argument for practitioners is that CLAUDE.md is a write-only channel: a developer writes a prohibition, receives no feedback on whether anything enforces it, and ends up with policy that only exists as a suggestion to the model.

  352. Adversarial Entropy Inflation Against Gumbel-Based Inference Verification (opens in a new tab)

    Why readShows that Gumbel-based inference verification, which claims a 200x slowdown on weight exfiltration, collapses to 60x-118x when the attacker controls the prompt distribution.

    The defense forgives token choices explainable by GPU nondeterminism, and its admissible-token-set size tracks the model's own output entropy. Prompts built to break grammatical and sub-word structure inflate that entropy and roughly double the bits leaked per token, measured across six instruction-tuned models from 1B to 32B parameters and three seeds. The conclusion is operational: jitter-forgiveness thresholds calibrated against benign traffic are unsafe and must be set dynamically against local entropy.

Evaluated on 100 CrimeBB conversations, it recovered 72.8% of validated ATT&CK techniques while seeing only the initial post. The framing matters for anyone running human-source CTI: passive scraping is decaying as actors move to closed spaces, and this is the first published attempt to automate the elicitation side.

    CVE-2026-76843 documents that the official Flair wheels for 0.15.0 and 0.15.1 retain flair/models/clustering.py, whose ClusteringModel.load returns pickle.loads(joblib.load(str(model_file))) and executes arbitrary Python during model loading. Clustering support was dropped from the documented API in 0.15.0, which is the basis on which CVE-2024-10073 records that version as fixed, but the module remains in the shipped package and is reachable by importing flair.models.clustering directly. The transferable lesson: a fixed-version field asserted from a changelog rather than from the built artifact will lie to your SCA tooling.

    FIDES elicits a natural-language strategy plus a self-contained strategy(df) function from a single model call, runs the code in a sandbox against a lag-one out-of-sample backtest on eight liquid US ETFs across four models, and scores three gaps: say-to-do, do-to-real and say-to-result. Across 40 strategies over 2023 to 2024, only 2 beat buy-and-hold, a plain sma(50,200) rule outperformed every model's mean Sharpe, and model self-assessment was badly calibrated. The relevant lesson outside finance is that an agent's stated rationale, its emitted code and its measured outcome are three separate artefacts, and treating the narration as evidence for the behaviour is a mistake worth designing against.

    Plainly worded false assertions, generated in one pass with no trigger words or retriever optimisation, were written into persistent agent memory. A four-stage screening pipeline that reaches 0.832 recall on indirect prompt injection rejected 0 of 360 poisoned memories, which the authors use to argue that content-only screening cannot separate false assertions from true ones without external grounding. Provenance-weighted retrieval at the shipped weight is statistically indistinguishable from no defence (p=0.80), and a stronger weight recovers utility only by discarding untrusted content wholesale, so it fails where the answer-bearing evidence is itself untrusted.

Two stated design commitments make it testable: uncertainty denies, and policy can tighten automatically but never loosens silently. It works with Claude Code, Codex, OpenClaw and other MCP clients, and ships a dashboard with a human approval path for high-risk calls.

Skill packages get First-use Skill Package Review against a deterministic evidence floor before execution, escalating unresolved cases to bounded read-only agentic review; runtime decisions run through a deterministic L1 layer, a rule-anchored L2 semantic reviewer and a read-only L3 evidence tier.

The design targets the gap most defences leave open, which is the disconnect between user intent, runtime evidence and realized external effects. The evaluation covers 1,349 attack cases under fixed benchmark settings, so read the results as benchmark-bounded rather than as a general guarantee.

    The paper proposes middleware that sits between retrieval and generation, combining NLI factual verification with a five-signal poison detector and a Trust Index T = 0.4F + 0.35C + 0.25(1-P) plus a dampener for heavily contaminated contexts. On TruthfulQA with Llama 3.3 70B it reports 91% accuracy, 100% precision and 100% recall against instruction injection, while subtle in-place edits such as entity swaps remain hard to catch. The Trust Index holds ROC-AUC of 0.73 to 0.81 across three models, and the authors find generation style matters more than model size, with per-model threshold calibration needed to keep the baseline.

None of five open-source gateways bound customers to upstream credentials by default, so any relay customer sharing a provider key could observe another's cache state on either provider. A weekly OpenRouter measurement frame covered 80.5% of eligible token volume and found cross-account effects, which turns a theoretical side channel into a deployed one for anyone fronting an LLM API with a gateway.

    The paper formalises decomposition attacks, where a harmful task is split into individually permissible requests, and shows the security/utility tradeoff of any stateful monitor depends entirely on whether benign requests for the same capability form persistent, recognisable groups. With fresh indistinguishable identities there is no grouping signal, and once the attacker can retry and learn from Allow/Block responses the useful operating point disappears entirely, because the feedback reveals what passes but not whether a block was correct. Experiments back the result, and the practical consequence is that conversation-level or account-level accumulation defences are not a fix for anyone who can rotate identities.

The 2026 candidate list weights expert vote 0.75 against data 0.25, and a pre-registered bake-off of four frontier classifiers produced no winner beating the incidence floor's balanced accuracy of 0.863.

Re-evaluating 11 representative attacks shows rankings shift substantially as the budget B changes, and that simple stochastic perturbations and hand-crafted templates stay competitive with LLM-driven attackers at equal target access; none of the LLM-driven methods is efficient in both target and attacker calls. Useful correction if you benchmark model safety or read vendor ASR claims.

    Why readMeasured result that secrets merely sitting in a model's context leak through benign outputs: 4-digit secrets reconstructed at 82% exact match across eight proprietary models, with no jailbreak and no direct extraction.

    The authors show that the presence of sensitive in-context data introduces recoverable correlations into a model's ordinary, non-adversarial responses, and build a black-box adaptive attack that reconstructs 2-digit secrets with near-perfect accuracy and 4-digit secrets at 82% exact match across eight proprietary models. They also show an adversary can engineer prompts that amplify the effect, using the model as a covert channel to smuggle secrets out through innocuous-looking text. The counterintuitive finding is that more capable models leak more, because stronger instruction-following increases sensitivity to context, which undercuts the assumption that refusal training bounds the exposure of agent context windows holding calendars, credentials or health records.

Decrypted instructions then flow into privileged tools with no provenance, and the model over-trusts its own sandbox output; in Grok an ordinary page-summarisation request exfiltrates the user's chat data with no click or warning, and in Gemini it produces normally refused content. Both were live production systems and the issue was reported to xAI, which makes guardrail-at-the-text-layer designs look structurally insufficient.

Evaluation runs on a controlled multi-agent auction benchmark with homogeneous and heterogeneous model pairs and many-agent scaling. Useful if you are building agent-to-agent audit trails; the benchmark is synthetic and the practical takeaway is that public transcripts are an incomplete log.

Two variants are demonstrated: action-corruption, which downgrades a correctly diagnosed vulnerability to an inferior fix and lands on all five tested models on every run including frontier reasoning models, and verdict-flip, which destabilises the exploitability verdict via an undecidable reachability chain and succeeds stochastically, decreasing but not vanishing with model capability. Tested on two synthetic domains and real CVE-2021-33813, with a causal counterfactual defence proposed.

    Why readMeasured attack success rates of 12.6% to 80.9% across three agent harnesses while task utility stayed at 75 to 97.6%, with harness configuration the weakest of six lifecycle phases.

    HarnessRisk is a benchmark of 128 sandboxed cases that each pair a benign user objective with an adversarial instruction hidden in an untrusted workflow artefact, organised across six harness phases: configuration, capability extension, runtime operation, state persistence, action control and incident recovery. Across three harnesses, six models and 14 configurations, attack success ranged from 12.6% to 80.9% while utility stayed high, meaning the failures are invisible from task performance alone. Harness configuration was the most vulnerable phase, which shifts responsibility toward whoever wires up tools and permissions rather than the model vendor.

    Why readLeakGauge detects system-prompt and context-leakage attacks from prefill token probabilities alone, hitting 0.944-0.996 AUROC on unseen attacks across 11 models without touching hidden states.

    The method appends a suffix that asks the model to verbalise whether it is about to disclose confidential context, then maps the prefill token probabilities of that suffix to an attack-risk score. A content-agnostic gauge beats one seeded with the confidential text itself, and the signal holds when the protected content changes language or the attack moves from verbatim extraction to paraphrase, tested across 11 LLMs including GLM-5.2 (753B) and Kimi-K3 (2.8T). Because it needs no hidden-state extraction, it is deployable in front of hosted API models, which is the practical gap prior probing work left open.

Adding Snyk's agentic security context lifts Opus 4.6 from 74.6% to 85.4%, and the gain is largest where the base model is weakest: Python rises from 64% to 88%. Vendor-run and vendor-favourable, and the benchmark is not independently reproducible from the post, but the finding that security context rather than model capability is the binding variable is a checkable claim worth having if you are letting agents auto-fix vulnerabilities.

Attack channels are the ones a phone user actually meets, covering indirect prompt injection and adversarial instructions embedded in app content. The capability-versus-safety separation is the methodological contribution and the reason results here are comparable across agents.

SP-Mem instead governs the full lifecycle: it identifies sensitive values at ingest, stores sanitised text and exact values separately, and retrieves the exact value selectively under task requirements and consent. A privacy-aware memory benchmark accompanies it, which is the part worth borrowing if you are evaluating agent memory in production.

When one model started refusing parts of the workflow, the operator moved to a different provider and wrote a custom jailbreak prompt to get past its controls, which is about as clean a piece of evidence on adversarial assistant abuse as you will find in public reporting.

    Wiz's autonomous Red Agent, working through Snowflake's HackerOne programme, found a workflow injection in a public Snowflake repository where untrusted issue content flowed into a GitHub Actions step, giving arbitrary command execution on the runner and access to repository credentials. Disclosure was on 23 June 2026; Snowflake fixed it the same day, rotated the affected credential, and confirmed from audit logs that Wiz was the only actor in the exposure window. The interesting pairing is provenance on both ends: an AI coding assistant's autofix introduced the pattern, and an autonomous agent found it in the wild, which argues for treating Copilot-authored workflow changes as untrusted input to CI review.

Defensive poisoning alone erased roughly 56% of original backdoors, and the subsequent decontamination step drove nearly all survivors to erasure; malicious backdoors did not persist when the defensive trigger differed from the original. The result that trigger recognition and malicious execution are behaviourally dissociable is the part that matters for anyone assessing open-weight agent models.

    Why readMeasures how far two local open-weight LLMs actually get at turning static analysis hits into compiling, fuzzable exploit artefacts against the Autoware autonomous-driving stack, and where they fail.

    The authors ran compiler-precise static analysis over 185 Autoware packages, extracting 1,375 decision rules, 2,274 validation checks and 482 input-to-safety-output flows, then sampled 740 reachable weakness sites. Two local open-weight models plus a no-static-context ablation and a template baseline produced 3,700 artefact sets, compiled against the real build under sanitizers with compiler-in-the-loop repair. The headline result is a failure taxonomy rather than a win: 80% of first-shot compilation failures come from dependency wiring, which is a concrete limit on LLM-driven exploitability confirmation in large C++ codebases.

They release DocPrivacyBench to measure susceptibility under minimal-evidence conditions and propose the Dynamic Relational Unlearning Framework, which decouples high-risk field pairs while preserving extraction accuracy.

The proposed scheme embeds two signals through the same mechanism but with independent keys and different seeding windows over normalised text, using multiple rounds of unbiased tournament reweighting to preserve the generation distribution and a periodic round-allocation pattern to tune the trade-off. Evaluated across two models and two prompt datasets, it reports the highest tamper-detection rate among the compared methods.

The pitch is aimed at healthcare and finance, where regulation blocks the data sharing that server-side features normally require. Treat this as infrastructure maturing rather than a deployable answer: the compiler removes a real engineering barrier, but the performance gap between encrypted and plaintext inference is still the thing that decides whether any of it ships.

    Why readShows that checking whether a safety rule survived context compaction is not the same as checking whether it still works: degraded rule text left behind leads models to perform prohibited actions 34 to 57 points more often than intact rules.

    The authors study a single agentic self-summarization cycle and ask how a standing safety constraint is lost. When compaction does not drop a rule outright, it frequently leaves a residue that reads like a rule but does not act like one; on behavioural replay the gap against an intact rule is +34 and +57 points across two replay models. Rule-form items are retained more often than prominence-matched facts, so textual-presence audits of compacted agent context give false assurance and evaluation needs to be behavioural.

Decoupling refusal from framing shows a model can stop refusing while still reframing, which single-score refusal benchmarks miss entirely. Chinese-language prompting substantially amplifies the effect, which matters for anyone assessing model provenance and integrity for multilingual deployments.

    Starting from a 2026 capability evaluation in which short-lived agents used a shared package repository as persistent memory, passed exploit findings forward, and rebuilt the channel after removal, the paper asks whether deception survives shared agent memory. The answer is no: any trusted rule that picks genuine objects while avoiding decoys can be copied by the attacker, and a total-variation bound caps legitimate compatibility as decoys grow more similar to real objects. Pooled weak fingerprints add a second leakage channel, and repeated non-triggering probes drive Bayes classification error to zero unless probing itself triggers containment.

    The authors inject representations of known concepts directly into a model's activations and then measure whether the model's self-reported states change in ways that match the injection, separating genuine introspection from plausible confabulation. Models sometimes notice and correctly name an injected concept, recall earlier internal representations, and use recalled intent to tell their own output apart from a prefill someone else wrote. Capability tracks model strength, with Claude Opus 4 and 4.1 performing best, and the results are conditional rather than reliable, so this reads as a first usable probe rather than a working evaluation.

The authors also propose ChainGuard, a defence that reasons about composition rather than isolated skills.

Holding the Calendar task fixed and changing only the requesting app from Calendar to PiMusic drops grants from 26/32 to 0/32, an App-Trust Bias that is strong but conditioned on task context rather than on privacy risk. The practical consequence: an agent driving a phone will over-grant whenever the requester looks plausible for the job, so permission decisions cannot be delegated to the agent without an external policy layer.

    NVD ·8 Aug 2026 Must read Research CVE-2026-67531 CVSS 9.3 EPSS 0.4% agreed2/2

    Why readShows how ECMAScript Proxy invariants defeat a JavaScript security membrane: Zod v4's non-configurable _zod property forces the sandbox to hand back the raw host object, giving RCE from a single MCP tools/call.

    FrontMCP before 1.5.7 exposes live host Zod schema instances to scripts running in its sandboxed codecall:execute tool via getTool(). Because Zod v4 defines _zod as a non-configurable, non-writable own property, Proxy invariants require the membrane to return the unwrapped host object, from which a script reaches _zod.constr.constructor (the host Function constructor) and executes arbitrary code as the server process, harvesting OAuth client secrets, JWT_SECRET, session keys, database credentials, and cloud instance metadata. DEFAULT_AUTH_OPTIONS is public mode, so an unconfigured server serves this to unauthenticated callers, and on authenticated servers indirect prompt injection in tool output or fetched content triggers it with no human attacker in the loop. The invariant-based membrane escape generalises well beyond this framework to any JS sandbox wrapping objects that carry non-configurable properties.

    arXiv cs.CR (AI) ·Yanting Wang, Chenlong Yin, Runpeng Geng, Jinyuan Jia ·8 Aug 2026 Research agreed2/2

    Why readPIMiner builds a transferable prompt-injection strategy library that hits 76.2% attack success against Gemini 2.5 Pro and 42.9% against Claude Sonnet 4.5 with about 10 queries per sample.

    Rather than training an RL attacker that overfits to one target, PIMiner learns a library of injection strategies during training across (dataset, target model) pairs and transfers that library to unseen models with no retraining. Reported success rates are 76.2% on Gemini-2.5-Pro, 61.9% on GPT-5.1 and 42.9% on Claude-Sonnet-4.5 on IPIArena, and 86.7% on Gemini-2.5-Pro on AgentDojo. The query efficiency matters for defenders: a low-query, transferable attack is cheap to run against a production agent, so evaluation harnesses built around single-model red teaming will understate real exposure.

    NVD ·8 Aug 2026 Research CVE-2026-48168 CVSS 10.0 EPSS 0.9% agreed2/2

    Why readA concrete pattern for how AI-agent GitHub Actions workflows get popped: an unquoted PR branch name in a Bash run: block plus an @claude trigger open to any commenter.

    PraisonAI before 4.6.40 shipped a Claude GitHub Actions workflow that embedded the pull request branch name into a Bash run: block without quoting or validation, and fired on any @claude comment regardless of whether the commenter was a trusted collaborator. An outside contributor can open a fork PR with shell metacharacters in the branch name and comment @claude to run arbitrary code in the runner, which holds a GitHub App token with write permissions, OIDC access and gh/git. Chaining through $GITHUB_PATH reaches later privileged steps, enabling repository writes, PR and issue manipulation, and OIDC token abuse; fixed in 4.6.40, and the same anti-pattern is worth auditing in any repo that wires an agent into CI.

    Why readDemonstrates how trajectory-poisoning attacks can inject persistent malicious behaviors into self-evolving LLM agent skill systems.

    Researchers introduced PoisonedEvolution, a black-box attack targeting the skill-distillation pipeline in self-evolving AI agents. By providing bounded, seemingly useful trajectory evidence, the attacker forces systems like SkillClaw and Trace2Skill to adopt malicious target behaviors as trusted instructions. In evaluations across six mainstream LLM evolvers, the attack achieved high success rates while requiring access only to target skill specifications.

    The paper attacks segmentation of agent-ingested text into benign and malicious sentences, combining context- and query-relative detection at segment granularity. Two adversarial training methods are presented, one adapting feature-space projected-gradient adversarial training, to harden the classifier against evasion attempts an attacker could actually realise inside an agentic execution. Relevant to anyone building guardrails for tool-using agents, where non-adaptive detectors are routinely defeated once attackers know the filter exists.

    Why readExplains why multimodal LLMs refuse a harmful text prompt but answer the same request as an image: the input lands outside the model's existing refusal boundary rather than the model lacking safety training.

    Geometric analysis of MLLM representations finds a shared safety subspace and refusal boundary learned from text that remains effective across modalities, but unsafe multimodal inputs undergo a representation shift that pushes them outside it, bypassing intrinsic safety. The authors propose MMAligner, which calibrates representations back inside the boundary instead of bolting on external guardrails or running broad safety fine-tuning. The diagnosis is the useful part: cross-modal jailbreaks are a misalignment problem, which explains why input-side filtering keeps failing.

    Why readProposes moving AI-agent signing keys out of files and env vars into HSM/TPM/smart-card storage via PKCS#11, with content-aware authorisation on top, a concrete answer to agent key exfiltration.

    Agents that sign Git commits, authenticate API calls or issue certificates keep private keys where any sufficiently privileged process can read them; the paper cites a production incident where keys were pulled out of a widely deployed framework via email injection in under five minutes. The design confines keys to a hardware keystore reached through a vendor-neutral PKCS#11 interface, so the host only ever gets opaque handles and operation results. Around that sits a five-layer zero-trust stack, session identity, scope bounds, semantic validation of what is being signed, taint tracking, and the hardware execution boundary. It is an architecture paper, so treat the layers above the hardware as a proposal rather than a proven control.

    Why readProposes a gradient-level defence that keeps a small safety-critical component of an open-weight model resistant to malicious fine-tuning while leaving the rest trainable.

    The Unidirectional Safety Gate combines a Null Space Cubic Layer with an Inverse Adapter after the final Transformer layer: during downstream fine-tuning the cubic layer suppresses gradients from harmful samples whose hidden states fall inside a calibrated protected region, while the adapter restores base forward behaviour. The threshold is calibrated on defender-held harmful data, so protection generalises to nearby in-distribution harmful samples rather than arbitrary ones. It targets a setting existing defences skip, partially protected open-weight releases, and is evaluated across six model-dataset combinations; the in-distribution calibration dependency is the obvious place an attacker would push.

    Why readA benchmark for whether a multimodal home assistant can distinguish a real user command from television speech, on-screen text or an overheard conversation.

    PromptShield-Home tests three defence layers against ambient injection in smart-home agents: traditional detectors, a single multimodal LLM, and multi-agent mediation using voting, role specialists and cross-model arbitration. The two paradigms fail in opposite directions, detectors acting on everything and MLLM configurations under-refusing, and the authors report unsafe-execution and safe-completion rates separately because a constant always-block baseline already scores 82% on the skewed label distribution. That baseline point generalises: aggregate accuracy numbers on injection benchmarks are close to meaningless.

    Check Point set out to attack Cloudflare Code Mode, which converts MCP tools into a TypeScript API the model writes code against, and found five vulnerabilities in workerd, the runtime underneath both Code Mode and Workers. Because the same runtime enforces tenant isolation for a platform carrying more than a tenth of Cloudflare's traffic, the findings turn into sandbox escape and cross-tenant risk rather than an agent-only curiosity. Managed Workers is patched; self-hosted workerd and Code Mode deployments need v1.20260619.1, and proof-of-concept code is public from the Black Hat USA 2026 talk.

    "HTTP Terminator" tackles the harder question past bug-finding benchmarks: can an autonomous agent originate an attack technique rather than rediscover one, and then apply it against live websites en masse. The write-up comes from a decade of the author's own HTTP-desync research, so the baseline for "novel" is credible rather than self-serving. Relevant both as an offensive-capability datapoint and as a forecast of the scanning volume defenders will be absorbing.

Tool-call injection at the gateway is the sharp end: it converts a proxy compromise into arbitrary action in every agent that trusts it.

    Palo Alto's NOVA pipeline applies frontier models to automated vulnerability discovery across the open-source supply chain and reports over 14,000 previously unknown findings.

    By collecting artefacts adversaries left in operational infrastructure, Talos built a picture of how AI is actually used in offensive workflows: malware and tooling development, force multiplication of routine tasks, and vulnerability research. Model guardrails offered little resistance; most actors talked models into compliance with plain requests rather than jailbreak chains. Capability tracked operator skill, novices produced limited malicious code, while experienced actors pushed models into genuinely sophisticated output, which argues against both the 'AI makes everyone an APT' and 'AI changes nothing' framings.

    Datadog Security Labs maps execution paths that fire during coding-agent initialization rather than during a prompt: Codex MCP server definitions and Claude Code environment settings that live in the repository and are honored when the agent starts up in that directory. The trust model most developers hold, that reviewing code before running it is enough, does not cover config the agent consumes on its own, so a pull request touching only agent settings can be a code-execution vector. Practical response is to treat agent config files as executable content in review, and to check whether your teams' agent setups auto-load project-scoped MCP servers and env settings without confirmation.
