CVE-2026-9096Network attack vector

Authentication bypass via discarded SAML time warnings

Published May 28, 2026 · Updated May 28, 2026

Insufficient SAML assertion expiration in Casdoor 2.362.0 and earlier allows remote attackers to obtain authenticated sessions. ParseSamlResponse() maps RetrieveAssertionInfo() output to a user session without reading WarningInfo, discarding NotBefore and NotOnOrAfter failures. A validly issued assertion outside its allowed time window is required, and reuse grants a session for its subject, including an administrator.
