Description
A flaw was found in org.keycloak.broker.saml. When a disabled Security Assertion Markup Language (SAML) client is configured as an Identity Provider (IdP)-initiated broker landing target, it can still complete the login process and establish a Single Sign-On (SSO) session. This allows a remote attacker to gain unauthorized access to other enabled clients without re-authentication, effectively bypassing security restrictions.
Affected configurations
• redhat build of keycloak
• redhat build of keycloak 26.2
• redhat build of keycloak 26.2.14
• redhat build of keycloak 26.4
• redhat build of keycloak 26.4.10
• redhat keycloak
