This is due to the `check_permissions()` method only checking for `edit_posts` capability instead of an administrator-level capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to list, create, modify, toggle, duplicate, and delete site-wide content restriction rules, potentially exposing restricted content or denying legitimate user access."}, {"lang": "es", "value": "El plugin User Registration & Membership para WordPress es vulnerable a la modificaci\u00f3n no autorizada de datos debido a una comprobaci\u00f3n de capacidad faltante en los endpoints de la API REST de Reglas de Acceso al Contenido en las versiones 5.0.1 a 5.1.4. Esto se debe a que el m\u00e9todo 'check_permissions()' solo comprueba la capacidad 'edit_posts' en lugar de una capacidad de nivel de administrador. Esto hace posible que atacantes autenticados, con acceso de nivel de Colaborador y superior, puedan listar, crear, modificar, alternar, duplicar y eliminar reglas de restricci\u00f3n de contenido de todo el sitio, exponiendo potencialmente contenido restringido o denegando el acceso a usuarios leg\u00edtimos."}], "lastModified": "2026-03-24T15:53:48.067", "sourceIdentifier": "security@wordfence.com"}
