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.
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_condition_update` AJAX action. This is due to the `validate_reqeust()` method using `current_user_can('edit_posts', $template_id)` instead of `current_user_can('edit_post', $template_id)` — failing to perform object-level authorization. Additionally, the `ha_get_current_condition` AJAX action lacks a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to modify the display conditions of any published `ha_library` template. Because the `cond_to_html()` renderer outputs condition values into HTML attributes without proper escaping (using string concatenation instead of `esc_attr()`), an attacker can inject event handler attributes (e.g., `onmouseover`) that execute JavaScript when an administrator views the Template Conditions panel, resulting in Stored Cross-Site Scripting.
