Magical Addons For Elementor < 1.1.40 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The Magical Addons For Elementor ( Header Footer Builder, Free Elementor Widgets, Elementor Templates Library ) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘_id’ parameter in all versions up to, and including, 1.1.39 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.
