CVSS v3.1

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Casdoor versions prior to 2.362.1

Description The SAML service provider implementation fails to validate the AudienceRestriction element in SAML assertions. This occurs because the buildSp() function in object/saml sp.go does not set the AudienceURI on the gosaml2 SAMLServiceProvider struct and ignores WarningInfo.NotInAudience. Consequently, the system may accept assertions intended for other service providers.

Recommendations Update Casdoor to version 2.362.1 or later.
