WP File Download <= 6.3.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary File Deletion/Modification via 'task' Parameter to Multiple Functions
The WP File Download plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.3.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to permanently delete any file managed by WP File Download, empty the entire trash, move files between categories, and publish or unpublish arbitrary files.
