Royal Elementor Addons Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Royal Elementor Addons plugin for WordPress, affecting versions through 1.7.1056. The issue arises in the Image Grid/Slider/Carousel widget, where insufficient output escaping in the render_post_thumbnail() function allows authenticated users with Author-level access and above to inject arbitrary scripts into image captions. These scripts are executed when a user views a page with the affected image displayed in the media grid widget.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users can update to version 1.7.1057 or a newer patched version to address this vulnerability.
