# CVE-2021-24205: Elementor \< 3.1.2 - Authenticated Stored Cross-Site Scripting (XSS) in Icon Box Widget

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 3.1.4
- Published: 2021-04-05 · Updated: 2024-08-03

## Affected

- Unknown Elementor Website Builder: from 3.1.4, fixed in 3.1.4

## Description

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.
