The application's session management relies on periodic cleanup to expire sessions instead of checking the last-access time when a session is loaded. As a result, an expired session whose record has not yet been cleaned up can still be replayed and used, allowing an attacker holding a previously valid session cookie to continue accessing protected resources after the configured idle timeout."}], "lastModified": "2026-09-22T20:17:08.790", "sourceIdentifier": "cve@mitre.org"}
