AI-suggested
Currently, no effective mitigation is available that meets Red Hat's criteria for ease of use, deployment, applicability, or stability. Users should monitor vendor advisories for future patches or fixes. Since this vulnerability requires the Organization feature and multiple organization memberships, limiting these configurations may reduce exposure. Check the Red Hat advisory for updates.
Description
A vulnerability in the Organization identity-first login flow of the Keycloak authentication server allows an attacker who is a member of multiple organizations to bypass authentication. The flaw occurs because a login success flag is not cleared properly when the user switches to registration or password reset paths, enabling the attacker to impersonate another user by providing their username. This results in full account takeover and access to connected applications.
