In version 1.6.5 and prior, cache-backed state/request-token storage is not tied to the initiating user session, so CSRF is possible for any attacker that has a valid state (easily obtainable via an attacker-initiated authentication flow). When a cache is supplied to the OAuth client registry, FrameworkIntegration.set_state_data writes the entire state blob under _state_{app}_{state}, and get_state_data ignores the caller\u2019s session altogether. This issue has been patched in version 1.6.6."}], "lastModified": "2026-01-22T17:04:38.110", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:authlib:authlib:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7E0D5D7A-D21C-445C-83BA-4DD3C66C5A0E", "versionEndExcluding": "1.6.6"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
