File Manager Advanced Shortcode <= Multiple Versions - Authenticated (Administrator+) Local JavaScript File Inclusion via Shortcode

The File Manager Advanced Shortcode plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.5.4 (file-manager-advanced-shortcode) and 2.5.6 (advanced-file-manager-pro-premium), via the 'file_manager_advanced' shortcode. This makes it possible for authenticated attackers, with Administrator-level access and above, to include and execute arbitrary JavaScript files on the server. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included. Sites currently using 2.5.4 (file-manager-advanced-shortcode) should be updated to 2.6.0 (advanced-file-manager-pro-premium).
