  "title": "OAuth client token authentication bypass in auth-framework",
  "summary": "Affected auth-framework releases may accept an OAuth client access token where an authenticated user session is required. An attacker operating a registered OAuth client could use such a token with user-protected endpoints; exposure requires the ability to obtain a client token. Tokens issued before an upgrade may remain usable until they expire.",
  "mitigation": "Upgrade auth-framework to 0.4.46, 0.5.0-rc82, or 0.6.0-rc46, as appropriate for the release line. For routes intended to accept delegated access, use the delegated-token validation provided by the fixed releases and account for previously issued client tokens until expiration.",
