CVE-2026-14615

A flaw was found in the Fine-Grained Admin Permissions (FGAP) v2 implementation within Keycloak's administrative services. When FGAP v2 is enabled, the system fails to properly filter child groups based on the caller's specific permissions when requested through a parent group. This allows a delegated administrator to view details of child groups they are not authorized to access directly, including group names, paths, and custom attributes.

Summary		(es) Se encontró una falla en la implementación de Permisos Administrativos Granulares (FGAP) v2 dentro de los servicios administrativos de Keycloak. Cuando se habilita FGAP v2, el sistema falla al filtrar correctamente los grupos secundarios basándose en los permisos específicos del solicitante cuando se solicitan a través de un grupo padre. Esto permite a un administrador delegado ver detalles de grupos secundarios a los que no está autorizado a acceder directamente, incluyendo nombres de grupo, rutas y atributos personalizados.
