Master Addons – Free Widgets, Hover Effects, Toggle, Conditions, Animations for Elementor <= 2.0.6.1 - Missing Authorization to Unauthenticated Stored Cross-Site Scripting via Navigation Menu Widget

The Master Addons – Free Widgets, Hover Effects, Toggle, Conditions, Animations for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Navigation Menu widget of the plugin's Mega Menu extension in all versions up to, and including, 2.0.6.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
