FileOrganizer <= 1.0.9 - Authenticated (Subscriber+) Arbitrary File Upload

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.

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: FileOrganizer 1.1.0 closes this, and updating the plugin is the step that ends it.
