The ParseSamlResponse() function in object/saml_sp.go calls sp.RetrieveAssertionInfo() and immediately maps the result to a user session. There is no assertion ID cache, OneTimeUse condition enforcement, or replay detection anywhere in the SAML SP code path. As a result, an attacker can replay a previously captured SAML assertion to obtain an authenticated session for the assertion\u2019s subject, including administrator accounts, without needing the user\u2019s password or MFA credentials."}], "lastModified": "2026-06-17T11:04:49.490", "sourceIdentifier": "cret@cert.org"}
