  "title": "Improper JWT validation in auth-framework",
  "summary": "auth-framework 0.4.x does not consistently enforce JWT validity claims such as expiration, issuer, audience, and token type when applications rely on its validator. An attacker able to submit a token to affected token-exchange or related validation flows may have expired or otherwise unsuitable tokens accepted; an introspection-related path can also treat a decodable token with an invalid signature as valid. Exposure depends on an application trusting these affected validation results.",
  "mitigation": "Upgrade auth-framework to 0.5.0-rc87 or later and configure the accepted issuers and audiences. Until upgraded, independently enforce expiration, not-before, issuer, and audience checks, and verify JWT signatures before using introspection-based validation paths.",
