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 modificación no autorizada de datos debido a una comprobación 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 método 'check_permissions()' solo comprueba la capacidad 'edit_posts' en lugar de una capacidad de nivel de administrador.
