CVE-2026-9091: Casdoor allows users to bypass configured MFA requirements

May 28, 2026 (updated July 2, 2026)

Casdoor versions 2.362.0 and earlier contain a logic flaw in the social‑login binding flow that allows users to bypass configured MFA requirements. The binding‑rule code path in controllers/auth.go calls HandleLoggedIn directly without invoking checkMfaEnable. Any user authenticating via this path is logged in without MFA enforcement.
