CVE-2026-3047

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.

Se encontró una vulnerabilidad en org.keycloak.broker.saml. Cuando un cliente de Security Assertion Markup Language (SAML) deshabilitado se configura como un objetivo de aterrizaje de intermediario iniciado por un Proveedor de Identidad (IdP), aún puede completar el proceso de inicio de sesión y establecer una sesión de Single Sign-On (SSO). Esto permite a un atacante remoto obtener acceso no autorizado a otros clientes habilitados sin re-autenticación, eludiendo eficazmente las restricciones de seguridad.
