CVE-2021-24205: Elementor Website Builder

Medium severity, CVSS 5.4. EPSS: 0.8% chance of exploitation in the next 30 days.

In the Elementor Website Builder WordPress plugin before 3.1.4, the icon box widget (includes/widgets/icon-box.php) accepts a ‘title_size’ 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_size’ parameter, which is not filtered and is output without escaping. This JavaScript will then be executed when the saved page is viewed or previewed.
