Official description

In the Elementor Website Builder WordPress plugin before 3.1.4, the accordion widget (includes/widgets/accordion.php) accepts a ‘title_html_tag’ parameter. Although the element control lists a fixed set of possible html tags, it is possible for a user with Contributor or above permissions to send a modified ‘save_builder’ request containing JavaScript in the ‘title_html_tag’ parameter, which is not filtered and is output without escaping. This JavaScript will then be executed when the saved page is viewed or previewed.
