SAML AudienceRestriction Validation Flaw in Casdoor
Publication date: 2026-05-28
Last updated on: 2026-05-28
Assigner: CERT/CC
Description
Description
In Casdoor versions 2.362.0 and earlier, the SAML service provider implementation does not validate the AudienceRestriction element in SAML assertions. The buildSp function in object/saml_sp.go never sets AudienceURI on the gosaml2 SAMLServiceProvider struct and never inspects WarningInfo.NotInAudience. This allows assertions issued for other service providers to be accepted by Casdoor.
