This link is maintained to preserve external references.\n\n## Original Description\n### Background\nSAML messages are usually signed to prove the identity of the issuer of the message. In the case of SAML authentication responses, correctly verifying the signature is critical to trust that the assertion contained inside the response was issued by a trusted third-party and the identity of the subject has been properly verified.\n\nA SAML message can be signed both at the message level and at the assertion level (if the message is an authentication response). When the whole authentication response message is unsigned, all the assertions contained inside must be signed independently in order to verify their authenticity. Failure to properly verify the authenticity of the entire message or individual assertions leads to the ability of an attacker to impersonate any user from any Identity Provider trusted by the Service Provider.\n\n### Description\nA signature validation bypass issue has been found in the `SimpleSAML_XML_Validator` class. This class performs the verification of the XML digi","public_affected_ranges":["ECOSYSTEM: introduced 1.12.0; fixed 1.14.17"]}],"null_published_at":"2026-10-31T22:13:01.463Z","source_updated_at":"2026-02-03T03:07:54.500Z","source_disclosed_at":"2024-05-28T19:29:37.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:42:20.405Z"}],"next_cursor":null,"snapshot_revision":"42594"}
