Here is my patch, found this issue after I coded it up and was looking for a way to send it to the developer. Hope s/he starts checking these issues.

Thanks Ryan, that did the trick. The security concern is valid based on the input data my script uses; However the WordPress instance that I use this script for is purely there for cmd line purposes so it wouldn’t affect any HTTP requests to the live site in any way (if that was somehow possible otherwise, maybe if this was used in a plugin it would be possible to break the site).
