The Plus Addons for Elementor <= 5.5.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via Progress Bar, Header Meta Content, Scroll Navigation, Pricing Table, & Flip Box

Vulnerability Description

The The Plus Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several of the plugin's widgets all versions up to, and including, 5.5.4 due to insufficient input sanitization and output escaping on user supplied attributes. 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. CVE-2024-35709 is likely a duplicate of this issue.
