CVE-2025-10939

A flaw was found in Keycloak. The Keycloak guides recommend to not expose /admin path to the outside in case the installation is using a proxy. The issue occurs at least via ha-proxy, as it can be tricked to using relative/non-normalized paths to access the /admin application path relative to /realms which is expected to be exposed.

Summary		(es) Se encontró una falla en Keycloak. Las guías de Keycloak recomiendan no exponer la ruta /admin al exterior si la instalación está utilizando un proxy. El problema ocurre al menos a través de ha-proxy, ya que se le puede engañar para que use rutas relativas/no normalizadas para acceder a la ruta de aplicación /admin relativa a /realms, que se espera que esté expuesta.
