This post was not real. It was an attempt at humor, as bad as it may seem. The post has been removed, and we understand the concerns. We truly apologize for misleading anyone. There is no vulnerability with WordPress 3.x. WordPress and its development team take serious all security considerations and do a great job of ensuring the WordPress security posture, we were not trying to undermine their hard work.
This is to be taken about as serious as most things on April 1st. Sorry for any inconvenience!
