HT Contact Form 7 <= 2.0.0 - Authenticated (Administrator+) Local File Inclusion

The HT Contact Form 7 plugin for WordPress is vulnerable to Local File Inclusion in versions up to, and including, 2.0.0. This makes it possible for authenticated attackers, with administrator-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
