Element Pack Elementor Addons (Header Footer, Template Library, Dynamic Grid & Carousel, Remote Arrows) < 5.10.3 - Authenticated (Contributor+ Stored Cross-Site Scripting via Open Map Widget

Description

The Element Pack Elementor Addons (Header Footer, Template Library, Dynamic Grid & Carousel, Remote Arrows) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Open Map Widget' marker_content parameter in all versions up to, and including, 5.10.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
