What the vulnerability does
01Description
The Tutor LMS Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'course_carousel_skin' attribute within the plugin's Course Carousel widget in all versions up to, and including, 2.1.4 due to insufficient input sanitization and output escaping on user supplied attributes.
