Summary

The FileBird – WordPress Media Library Folders & File Manager plugin for WordPress is vulnerable to missing authorization in all versions up to and including 6.5.1 via the "ConvertController::insertToNewTable" function due to missing validation on a user-controlled key. This allows authenticated attackers with author level access and above to inject global folders and reassign arbitrary media attachments to those folders under certain circumstances.

Risk Assessment

The risk includes the ability to manipulate folder structure and attachment assignments, which could lead to unauthorized access to files or data integrity compromise.

Recommendation

Update the FileBird plugin to the latest patched version. Also restrict user permissions and monitor folder-related actions.
