CVE-2021-24204: Elementor < 3.1.2 - Authenticated Stored Cross-Site Scripting (XSS) in Accordion Widget

Published Apr 5, 2021
·
Updated

In the Elementor Website Builder WordPress plugin before 3.1.4, the accordion widget (includes/widgets/accordion.php) accepts a ‘titlehtmltag’ 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 ‘savebuilder’ request containing JavaScript in the ‘titlehtmltag’ parameter, which is not filtered and is output without escaping. This JavaScript will then be executed when the saved page is viewed or previewed.
