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 plugin's widgets in all versions up to, and including, 5.7.6 due to insufficient input sanitization and output escaping on user supplied attributes like 'title_tag'. 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.
