CVE, Research URL: CVE-2021-24206
Home page URL: Security reports for Elementor Website Builder – More than Just a Page Builder
Application: Elementor Website Builder – More than Just a Page Builder
Published on: Apr 06, 2021
Research Description: In the Elementor Website Builder WordPress plugin before 3.1.4, the image box widget (includes/widgets/image-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.
Affected versions: Min -, max 3.1.4.
Status: vulnerable
