Descriptions

keycloak before version 4.0.0.final is vulnerable to a infinite loop in session replacement. A Keycloak cluster with multiple nodes could mishandle an expired session replacement and lead to an infinite loop. A malicious authenticated user could use this flaw to achieve Denial of Service on the server.

keycloak en versiones anteriores a la 4.0.0.final es vulnerable a un bucle infinito en el reemplazo de sesiones. Un clúster de Keycloak con múltiples nodos podría gestionar erróneamente un reemplazo de sesión erróneo y conducir a un bucle infinito. Un usuario autenticado malicioso podría emplear este error para lograr una denegación de servicio (DoS) en el servidor.
