AI-suggested
Red Hat states that mitigation options are either unavailable or do not meet criteria for ease of use, applicability, or stability. Users should monitor vendor advisories for updates and consider the risk of enabling client policies enforcing 2FA for users not yet enrolled.
Description
A vulnerability in Keycloak's authentication session management allows bypassing mandatory two-factor authentication (2FA) setup enforced by client policy. By visiting a specific session restart endpoint during login, a user can clear internal markers tracking required security steps and log in with only a password. This flaw requires a specific server-side configuration and affects only users not yet enrolled in 2FA. The vulnerability is rated low severity by Red Hat.
