Description
The HappyAddons for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure via the Team Member widget's lightbox template setting (saved_template_list) in versions 3.0.0 up to, and including, 3.51.0, due to the plugin passing the user-supplied post ID to Elementor's get_builder_content_for_display() without checking that it is a published Elementor template. This makes it possible for authenticated attackers, with contributor-level access and above, to render and view the Elementor content of arbitrary posts, including private and draft posts they should not have access to.
