Description
A flaw was found in the authentication session management of Keycloak, an identity and access management solution. The issue occurs when an administrator enforces a stronger authentication flow, such as mandatory two-factor authentication (2FA) setup, through a client policy. A user can bypass this requirement by manually visiting a specific session restart web link during the login process. This action clears the internal markers that track the required security steps, allowing the user to log in with only a password and gain access without completing the mandated 2FA setup.
