What is CVE-2021-24204?

CVE-2021-24204 is a medium-severity cross-site scripting vulnerability in Unknown Elementor Website Builder, published on 5 Apr 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

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.
