Executive Summary

Casdoor versions 2.362.0 and earlier have a vulnerability that allows an attacker to bypass authentication.

This happens because the buildSpCertificateStore function extracts the X.509 certificate directly from the incoming SAMLResponse instead of using the trusted pre-configured Identity Provider certificate.

As a result, an attacker can forge assertions signed with an attacker-controlled key, effectively bypassing authentication.
