## Description

The Premium Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the lightbox image URL of the Media Grid and Media Wheel widgets in all versions up to, and including, 4.11.111. This is due to the lightbox link URL being output without URL validation, and the bundled prettyPhoto lightbox script inserting that URL into its markup without escaping single quotes or restricting it to http(s) URLs. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute when a user opens the lightbox on an injected page.
