CVE-2026-33953

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.

Summary		(es) 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.
