Executive brief
The Plus Addons for Elementor, a popular WordPress plugin used for building custom website layouts and menus, contains a security flaw in its Navigation Menu Lite widget. This vulnerability allows users with contributor-level access or higher to inject malicious scripts into website pages. When other users, including site administrators or visitors, view these pages, the scripts will execute in their browsers, potentially leading to unauthorized actions or data theft.
Technical details
The Plus Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'menu_hover_click' parameter within the Navigation Menu Lite widget.

These scripts will execute in the context of any user's browser who visits the affected page. The issue was addressed in version 6.4.12 by implementing proper sanitization and escaping functions.
