Zombify <= 1.7.5 - Authenticated (Subscriber+) Path Traversal to Arbitrary File Read

The Zombify plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.7.5. This is due to insufficient input validation in the zf_get_file_by_url function. This makes it possible for authenticated attackers, with subscriber-level access and above, to read arbitrary files on the server, including sensitive system files like /etc/passwd, via a forged request. It's worth noting that successfully exploiting this vulnerability relies on a race condition as the file generated will be deleted immediately.
