DescriptionCVE.org

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.

AnalysisAI

Unauthorized post duplication in Happy Addons for Elementor (WordPress plugin) versions up to 3.21.0 allows authenticated contributors and above to clone any published content by reusing a nonce from their own posts and modifying the target post ID. The vulnerability stems from insufficient object-level permission checks in the duplicate function, which only validates generic edit capabilities rather than verifying access to specific posts. Attackers can exploit this to duplicate other users' posts, pages, or custom post types without authorization.
