Description

The Jeg Kit for Elementor – Powerful Addons for Elementor, Widgets & Templates for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.2.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the targeted post also renders a legitimate Jeg Kit Countdown widget, which causes the countdown frontend script to be enqueued and to initialize on any matching DOM element — including forged widget markup stored in comments.

• CWE-79Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
