CVE-2024-4643 Element Pack Elementor Addons (Header Footer, Template Library, Dynamic Grid & Carousel, Remote Arrows) <= 5.7.1 - Authenticated (Contributor+) Stored Cross-Site Scripting

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 ‘end_redirect_link’ parameter in versions up to, and including, 5.7.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
