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 user-supplied attributes within the Progress Bar shortcode. This vulnerability allows authenticated attackers with contributor-level permissions or higher to inject arbitrary web scripts into pages. These scripts are stored on the server and execute in the context of a user's browser session whenever they visit the compromised page. The issue affects all versions up to and including 6.4.9 and has been addressed in subsequent updates.
