Description
phpMyFAQ 3.2.0-alpha before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an authentication bypass vulnerability that allows IdP-authenticated users to skip TOTP two-factor authentication through the Keycloak and Entra ID SSO callbacks. Attackers holding a valid or phished IdP identity linked to a 2FA-enabled account can complete the OIDC flow and obtain a fully authenticated session, including administrator accounts.
