      "value": "LinkAce is a self-hosted archive to collect website links. Versions prior to 2.5.3 block direct requests to private IP literals, but still performs server-side requests to internal-only resources when those resources are referenced through an internal hostname. This allows an authenticated user to trigger server-side requests to internal services reachable by the LinkAce server but not directly reachable by an external user. Version 2.5.3 patches the issue."

      "value": "LinkAce es un archivo autoalojado para recopilar enlaces de sitios web. Las versiones anteriores a la 2.5.3 bloquean las solicitudes directas a literales de IP privadas, pero aún realizan solicitudes del lado del servidor a recursos solo internos cuando esos recursos son referenciados a través de un nombre de host interno. Esto permite a un usuario autenticado activar solicitudes del lado del servidor a servicios internos accesibles por el servidor LinkAce pero no directamente accesibles por un usuario externo. La versión 2.5.3 corrige el problema."
