      "value": "The Post Duplicator plugin for WordPress is vulnerable to unauthorized arbitrary protected post meta insertion in all versions up to, and including, 3.0.8. This is due to the `duplicate_post()` function in `includes/api.php` using `$wpdb-\u003einsert()` directly to the `wp_postmeta` table instead of WordPress\u0027s standard `add_post_meta()` function, which would call `is_protected_meta()` to prevent lower-privileged users from setting protected meta keys (those starting with `_`). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary protected post meta keys such as `_wp_page_template`, `_wp_attached_file`, and other sensitive meta keys on duplicated posts via the `customMetaData` JSON array parameter in the `/wp-json/post-duplicator/v1/duplicate-post` REST API endpoint."

Esto se debe a que la funci\u00f3n `duplicate_post()` en `includes/api.php` utiliza `$wpdb-\u0026gt;insert()` directamente en la tabla `wp_postmeta` en lugar de la funci\u00f3n est\u00e1ndar de WordPress `add_post_meta()`, la cual llamar\u00eda a `is_protected_meta()` para evitar que usuarios con privilegios inferiores establezcan claves de metadatos protegidas (aquellas que comienzan con `_`). Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, inyecten claves de metadatos de publicaci\u00f3n protegidas arbitrarias como `_wp_page_template`, `_wp_attached_file` y otras claves de metadatos sensibles en publicaciones duplicadas a trav\u00e9s del par\u00e1metro de array JSON `customMetaData` en el endpoint de la API REST `/wp-json/post-duplicator/v1/duplicate-post`."
