## Description

The HappyAddons for Elementor plugin for WordPress is vulnerable to unauthorized modification of data in versions 3.2.0 up to, and including, 3.51.0 due to the setup wizard REST routes checking only the edit_others_posts capability instead of manage_options. This makes it possible for authenticated attackers, with editor-level access and above, to change plugin settings such as deactivating widgets and features, enabling the usage tracking consent option, and storing arbitrary data in the wizard cache option.
