Elementor Website Builder <= 3.5.5 - Unauthenticated DOM-based Reflected Cross-Site Scripting

The Elementor Website Builder plugin for WordPress is vulnerable to Unauthenticated DOM-based Reflected Cross-Site Scripting via the ‘videoType’ and 'onError' parameter in the lightbox module in versions up to, and including, 3.5.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
