The Bit File Manager – 100% Free & Open Source File Manager and Code Editor for WordPress plugin for WordPress is vulnerable to Limited JavaScript File Upload in all versions up to, and including, 6.5.7. This is due to a lack of proper checks on allowed file types. This makes it possible for authenticated attackers, with Subscriber-level access and above, and granted permissions by an administrator, to upload .css and .js files, which could lead to Stored Cross-Site Scripting.

Multiple plugins and/or themes for WordPress are vulnerable to Limited File Upload in various versions. This is due to a lack of proper checks to ensure lower-privileged roles cannot upload .css and .js files to arbitrary directories. This makes it possible for authenticated attackers, with Subscriber-level access and above, and granted permissions by an administrator, to upload .css and .js files to any directory within the WordPress root directory, which could lead to Stored Cross-Site Scripting. The Advanced File Manager Shortcodes plugin must be installed to exploit this vulnerability.
