Esto se debe a que el plugin registra m\u00faltiples rutas de la API REST bajo 'generateblocks/v1/meta/' que restringen el acceso con 'current_user_can('edit_posts')', lo cual se concede a roles de bajo privilegio como Colaborador. Los manejadores aceptan IDs de entidad arbitrarios (IDs de usuario, IDs de publicaci\u00f3n, etc.) y claves meta, devolviendo cualquier metadato solicitado con solo una corta lista negra de claves similares a contrase\u00f1as para protecci\u00f3n. No hay autorizaci\u00f3n a nivel de objeto que asegure que el llamador est\u00e1 solicitando solo sus propios datos, y no hay una lista blanca de claves seguras. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, exfiltren informaci\u00f3n de identificaci\u00f3n personal (PII) y otros datos de perfil sensibles de cuentas de administrador o de cualquier otro usuario consultando directamente las claves meta de usuario a trav\u00e9s de los puntos finales expuestos mediante la funci\u00f3n 'get_user_meta_rest'.
