The Elementor Website Builder Pro plugin for WordPress contains a stored XSS vulnerability (CWE-79) in its Media Carousel widget. This occurs because the plugin does not properly sanitize or escape user input in widget attributes, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript code. This malicious code executes in the context of any user who views the compromised page, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 3.20.1. The CVSS 3.1 base score is 5.4 (medium severity), reflecting network attack vector, low attack complexity, and required privileges. There is no indication of an official patch or vendor advisory at this time.

Successful exploitation allows authenticated users with contributor-level or higher permissions to inject persistent malicious scripts into pages via the Media Carousel widget. These scripts execute in the browsers of users who visit the infected pages, potentially leading to information disclosure or other client-side impacts. The vulnerability does not allow privilege escalation or denial of service according to the available data. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level permissions to trusted users only and consider disabling or avoiding use of the Media Carousel widget in affected versions. Monitor official Elementor channels for updates and apply patches promptly once available.
