Technical details

The WP Customer Area plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'type' attribute of the `customer-area-protected-content` shortcode. An authenticated attacker with Contributor-level access or higher can exploit this by injecting arbitrary web scripts into a page via the shortcode. Because the script is stored on the server, it executes in the browser of any user who views the compromised page. This vulnerability was addressed in version 8.3.6.
