Under certain circumstances, a valid assertion may be replayed within its validity period, potentially allowing repeated authentication attempts using the same assertion.\n\nThis vulnerability is mitigated by the fact that an attacker must first obtain a valid SAML assertion and can only reuse it during the assertion's validity period.","status":"published","published":"2026-09-09T17:23:14Z","modified":"2026-09-09T19:25:58.582607Z","updated_at":"2026-11-02T15:46:13.900249Z"}]}}
