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 AJAX action. This is due to the method using instead of — failing to perform object-level authorization. Additionally, the 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 template.
