CVE-2026-2917
The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_duplicate_thing` admin action handler. This is due to the `can_clone()` method only checking `current_user_can('edit_posts')` (a general capability) without performing object-level authorization such as `current_user_can('edit_post', $post_id)`, and the nonce being tied to the generic action name `ha_duplicate_thing` rather than to a specific post ID.

This makes it possible for authenticated attackers, with Contributor-level access and above, to clone any published post, page, or custom post type by obtaining a valid clone nonce from their own posts and changing the `post_id` parameter to target other users' content. The clone operation copies the full post content, all post metadata (including potentially sensitive widget configurations and API tokens), and taxonomies into a new draft owned by the attacker.

"value": "El plugin Happy Addons for Elementor para WordPress es vulnerable a Referencia Directa Insegura a Objeto en todas las versiones hasta la 3.21.0, inclusive, a través del gestor de acción de administración 'ha_duplicate_thing'. Esto se debe a que el método 'can_clone()' solo verifica 'current_user_can('edit_posts')' (una capacidad general) sin realizar una autorización a nivel de objeto como 'current_user_can('edit_post', $post_id)', y a que el nonce está vinculado al nombre de acción genérico 'ha_duplicate_thing' en lugar de a un ID de publicación específico. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, clonen cualquier publicación, página o tipo de publicación personalizada publicada obteniendo un nonce de clonación válido de sus propias publicaciones y cambiando el parámetro 'post_id' para apuntar al contenido de otros usuarios. La operación de clonación copia el contenido completo de la publicación, todos los metadatos de la publicación (incluidas configuraciones de widgets y tokens de API potencialmente sensibles) y taxonomías en un nuevo borrador propiedad del atacante."
