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 – Manage WordPress and Website Files plugin for WordPress is vulnerable to Stored Cross-Site Scripting via svg file upload in all versions up to, and including, 1.0.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. For the free version, this is limited to administrators. The pro version is also vulnerable and exploitable by administrators, but also offers the functionality to lower level users (as low as subscribers) if enabled.

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.
