Black: GitHub Action installs unvalidated required-version from pyproject.toml
影響: pip:black < 26.10.1 → 26.10.1 The GitHub Action bundled with Black can read the version from tool.black.required-version if use_pyproject is set to True. This version is not validated and therefore can be used to execute untrusted code in the context of a victim's repository. Details This is similar to the previous CVE-2026-31900. The value in tool.black.required-version is accepted as the version to be installed by the action without validation. Proof of concept Reproduction requires a victim to use Black's GitHub Action w…

OpenChoreo: Authorization bypass on WorkflowRun update allows cross-project takeover of workflow runs
影響: go:github.com/openchoreo/openchoreo >= 1.0.0, < 1.0.6 → 1.0.6, go:github.com/openchoreo/openchoreo >= 1.1.0, < 1.1.7 → 1.1.7, go:github.com/openchoreo/openchoreo >= 1.2.0, < 1.2.5 → 1.2.5 The OpenChoreo API server authorized PUT .../workflowruns/{runName} against ownership metadata taken from the request body, while the object it actually mutated was selected by the URL path. Nothing forced the two to agree. A WorkflowRun's membership in a project and component is carried entirely by its openchoreo.dev/project and openchoreo.dev/component labels. Because the workflowrun:update check read those labels from the submitted object rather than the stored one, a caller holding…
Moov signedxml: Unauthenticated denial of service in exclusive XML canonicalization
影響: go:github.com/moov-io/signedxml <= 1.4.0 → 1.4.1 Exclusive XML canonicalization (http://www.w3.org/2001/10/xml-exc-c14n#) in github.com/moov-io/signedxml copied the entire accumulated namespace map at every node during ValidateReferences(), before any reference digest or signature check. For a chain of nested elements that each declare many unused namespace prefixes, that produced O(m × depth²) time and peak memory (m = prefixes per level). beevik/etree caps tree depth (~1024), but m is unbounded, so a small attacker-controlled document (on t…

A2A Java SDK has a fail-open default task authorization
影響: maven:org.a2aproject.sdk:a2a-java-sdk-server-common < 1.3.0.Final → 1.3.0.Final Draft text for GHSA-qw47-mcm5-934w. The body below drops into the GitHub advisory description field; the metadata block maps to the form fields. Set the patched version at release; publish when the fix ships._ --- - Ecosystem: Maven - Affected package: org.a2aproject.sdk:a2a-java-sdk-server-common (task store / authorization) - Affected versions: <= 1.2.0.Final (and 1.2.1.Final-SNAPSHOT on main prior to the fix) - Patched version: _(the release that carries the fix, e.g. 1.2.1.Final)_ - CWE: CW…
launch-editor: `fs.existsSync()` existence check can be bypassed on Windows
影響: npm:launch-editor <= 2.14.1 → 2.14.2, npm:vite >= 8.3.0, <= 8.3.2 → 8.3.3, npm:vite >= 8.2.0, <= 8.2.3 → 8.2.4, npm:vite >= 8.0.0, <= 8.1.5 → 8.1.6, npm:vite >= 7.0.0, <= 7.3.6 → 7.3.7, npm:vite <= 6.4.3 → 6.4.4, npm:vite-plus <= 1.0.0 → 1.1.0 launch-editor checked fs.existsSync(fileName) before passing a supplied path to an editor command. On Windows, an attacker can bypass this check with a crafted path ending in \\..:line:column. This removes the requirement that the attacker be able to place a file with a malicious filename. Combined with the % escaping issue described in [GHSA-698v-4r3x-3vcv](https://github.com/vitejs/launch-editor/security/advisories/GHSA-698v-4r3x-3vcv), this bypass can lead to OS command injection whe…
@angular/router: Denial of Service via RouterLink Query Parameter Retention in Server-Side Rendering (SSR)
影響: npm:@angular/router >= 22.0.0, < 22.2.1 → 22.2.1, npm:@angular/router >= 21.2.0, < 21.2.25 → 21.2.25 A denial of service (DoS) vulnerability was identified in @angular/router when Server-Side Rendering (SSR) is enabled on Node.js (V8) and RouterLink directives are rendered with queryParamsHandling: 'merge' or 'preserve', configured either per link or globally via defaultQueryParamsHandling. Starting in v21.2.0 ([angular/angular#66181](https://github.com/angular/angular/pull/66181)), RouterLink internals were refactored to use signals, introducing a computed signal (_urlTree) that cached the re…

Compress/s2: Integer Overflow or Wraparound and Out-of-bounds Write in compress
影響: go:github.com/klauspost/compress <= 1.18.6 → 1.18.7 Signed Integer Overflow in s2.NewDict Summary A signed integer overflow vulnerability in s2.NewDict() allows an attacker to bypass repeat index validation by supplying a dictionary with a uvarint-encoded repeat value exceeding MaxInt64. When Dict.Encode() is subsequently called, the overflowed negative repeat value causes an out-of-bounds memory access via unsafe.Pointer arithmetic, crashing the process with SIGSEGV. Package - Name: github.com/klauspost/compress/s2 - Ecosystem: Go - Affected ve…
Crass : Large numeric exponents cause CPU and memory denial of service
影響: rubygems:crass < 1.0.7 → 1.0.7 Crass converts CSS scientific notation number values with unbounded exponentiation before it clamps the result to Float::MAX. Applications that use Crass to parse attacker-controlled CSS strings can be forced to spend disproportionate CPU and memory parsing a tiny input, possibly resulting in a crash. Patches This is fixed in Crass 1.0.7. Related - https://github.com/rubysec/ruby-advisory-db/blob/master/gems/crass/GHSA-6wmf-3r64-vcwv.yml

Arcane: Delegated users:update permission allows admin account takeover via password reset (no privilege-hierarchy check)
影響: go:github.com/getarcaneapp/arcane/backend/v2 < 2.6.0 → 2.6.0 A user holding the delegated users:update permission can reset the global administrator's password and take over the admin account. UpdateUser sets the target user's PasswordHash from the request body for ANY target with no comparison of caller-vs-target privilege. Because role assignment and role CRUD are deliberately gated by RequireGlobalAdmin, users:update is intended to sit BELOW admin (profile management); this finding defeats that separation. Root Cause UpdateUser (handler backen…
kin-openapi openapi3filter: nil-pointer panic in ValidateResponse on a response header declared with content
影響: go:github.com/getkin/kin-openapi <= 0.145.0 → 0.146.0 ValidateResponse panics on a nil pointer when a spec declares a response header with content instead of schema. doc.Validate() accepts that document, so the crash comes from a spec the library just called valid. Same class as GHSA-jpcw-4wr7-c3vq, which covered the request-parameter case in v0.144.0; this is the response-header path. Affects github.com/getkin/kin-openapi 0 { Two things I checked rather than assumed. The response does not need to carry the header; declaring it is enough,…
gomarkdown/markdown IsSafeURL panics on short URLs
影響: go:github.com/gomarkdown/markdown < 0.0.0-20260724235538-61af6e1e6971 → 0.0.0-20260724235538-61af6e1e6971 IsSafeURL slices url[:nPath] before checking that len(url) >= nPath, so a URL shorter than a path prefix (0, 1 or 2 bytes) triggers a slice-bounds panic, and this is reached end to end when the html.Safelink hardening flag is enabled and the input contains an empty or very short link destination, giving an unrecoverable crash DoS. Confirmed at HEAD (e08cff8; present since 2022). The defect parser/parser.go, IsSafeURL: go func IsSafeURL(url []byte) bool { nLink := len(url) for _, path :=…

Podman: The `podman run` command can be instructed to disable almost all sandboxing by image annotation
影響: go:github.com/containers/podman >= 4.4.0, < 5.8.8 → 5.8.8, go:go.podman.io/podman/v6 >= 6.0.0, < 6.1.3 → 6.1.3 Podman v4.4.0 added a feature where container checkpoints (from the podman container checkpoint command) could be distributed via OCI registry, and pulled from that registry and run via the podman run command. This allowed easy transfer of checkpoints between systems. However, checkpoints allow complete control of how the container is created - including full control of the container sandbox. When podman run detects a checkpoint, it will silently ignore all user input regarding how the c…
containerd CRI plugin: Checkpoint restore bypasses destination security context
影響: go:github.com/containerd/containerd/v2 >= 2.1.0, < 2.2.7 → 2.2.7, go:github.com/containerd/containerd/v2 >= 2.3.0, < 2.3.4 → 2.3.4 A vulnerability in containerd's CRI implementation allows a container restored from an untrusted checkpoint via the CreateContainer API to bypass the destination security context and execute with elevated privileges. When restoring a container from a checkpoint archive or annotated OCI image, CRIU restores process credentials, Linux capabilities, no_new_privs, and seccomp state directly from checkpoint data rather than enforcing the destination CRI ContainerConfig. An attacker who can ru…
kin-openapi: Incomplete Fix for GHSA-p6wj-qrr4-pgh5: Three Unpatched nil-Items Panic Paths in openapi3filter
影響: go:github.com/getkin/kin-openapi >= 0.136.0, < 0.149.0 → 0.149.0 The fix for GHSA-p6wj-qrr4-pgh5 addressed a nil-pointer dereference that occurs when an OpenAPI 3.1 array schema omits the items keyword (which is legal under JSON Schema 2020-12). That fix patched three decoder paths: the standalone parseArray function, the top-level array check in UrlencodedBodyDecoder, and MultipartBodyDecoder. Three additional crash paths were missed. All of them reach the unguarded urlValuesDecoder.parseArray method (openapi3filter/req_resp_decoder.go:576) or the u…
