Why this deserves its current priority

CVSS is 7.6. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Analysis status

Analysis pending evidence review

Factual feed record only; HOL analysis is not approved for indexing. Read the methodology.

Affected scope and exposure questions

The current feed maps coder/coder (generic), coder/coder (generic), coder/coder (generic), coder/coder (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
PackageAffected rangeFixed version
coder/codergeneric>=2.38.0 <2.38.42.38.4
coder/codergeneric>=2.37.0 <2.37.82.37.8

coder/codergeneric>=2.35.0 <2.36.02.36.0

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for coder/coder, coder/coder, coder/coder.
  2. 2Review the reported fix. Update coder/coder to 2.38.4; coder/coder to 2.37.8; coder/coder to 2.36.11; coder/coder to 2.34.16; coder/coder to 2.29.24; coder/coder to 2.36.0 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

Coder 2.28.0 before 2.29.24, 2.30.0 before 2.34.16, 2.35.0 before 2.36.11, 2.37.0 before 2.37.8, and 2.38.0 before 2.38.4 does not restrict new API keys to the creating token's scopes, allow list, or expiry. A scoped API key or OAuth2 token holding key-creation permission can call POST /api/v2/users/{user}/keys/tokens to mint longer-lived coder:all keys, gaining the user's full privileges.
