CVE-2026-9092: Casdoor

Critical severity, CVSS 9.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
