The FileOrganizer – Manage WordPress and Website Files plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the "fileorganizer_ajax_handler" function in all versions up to, and including, 1.0.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, and permissions granted by an administrator, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: The FileOrganizer Pro plugin must be installed and active to allow Subscriber+ users to upload files.

The FileOrganizer – Manage WordPress and Website Files plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.0.7 via the 'fileorganizer_ajax_handler' function. This makes it possible for unauthenticated attackers to extract sensitive data including backups or other sensitive information if the files have been moved to the built-in Trash folder.

The FileOrganizer WordPress plugin through 1.0.2 does not restrict functionality on multisite instances, allowing site admins to gain full control over the server.
