  "title": "DPoP sender-constraint bypass in auth-framework",
  "summary": "Affected auth-framework FAPI paths may accept DPoP-bound tokens even when the accompanying proof does not satisfy required validation checks. An attacker who has obtained a DPoP-bound token could use it without controlling the token holder's key; this requires use of the affected FAPI/DPoP-bound token flows.",
  "mitigation": "Upgrade auth-framework to 0.4.47, 0.5.0-rc84, or 0.6.0-rc199, as appropriate for your release line. Until upgraded, disable or avoid FAPI flows that use DPoP-bound tokens.",
