## Description

The The Plus Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Video Player widget's YouTube ID, Vimeo ID and MP4 link settings in all versions up to, and including, 6.5.3, due to insufficient input sanitization. esc_attr() and esc_url() keep HTML entities such as encoded quotes, and the lightbox script reads the decoded link and concatenates it into iframe markup. 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 clicks the video on an injected page.
