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.
Monitor this advisory for an available fix and review any installs of the affected package.

AI coding agents often install or upgrade packages automatically in go. A critical vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
