Description

Casdoor versions 2.362.0 and earlier contain a vulnerability involving unverified email binding that may enable account takeover. The getExistUserByBindingRule function matches users by email without checking the email_verified claim from upstream providers; the idp.UserInfo struct does not even include a EmailVerified field. An attacker can supply an unverified email claim from an upstream provider to take over accounts that use the same email address.
