Download Manager <= 3.3.08 - Authenticated (Author+) Path Traversal to Limited File Overwrite

The Download Manager plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.3.08 via the 'wpdm_newfile' action. This makes it possible for authenticated attackers, with Author-level access and above, to overwrite select file types outside of the originally intended directory, which may cause a denial of service.
