  "title": "Improper DPoP-bound token validation in auth-framework",
  "summary": "auth-framework releases before 0.4.50, 0.5.0-rc86, and 0.6.0-rc202 can inadequately validate JWT access tokens through the legacy DPoP validation method. An attacker may cause an application to accept a token they did not obtain from a trusted issuer if the application relies on that method and accepts the result for authorization.",
  "mitigation": "Upgrade to auth-framework 0.4.50, 0.5.0-rc86, or 0.6.0-rc202, as appropriate. Until upgraded, stop using the legacy method and independently verify token signature, lifetime, issuer, audience, and the DPoP key binding before authorizing requests.",
