Title
Happy Addons for Elementor <= 3.21.0 - Insecure Direct Object Reference to Authenticated (Contributor+) Stored Cross-Site Scripting via Template Conditions
Summary
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.
