Did you update your WP blog with 2.1.2?

Critical update for Wordpress 2.1.1 - if using Fantasico - check the version cos on my hosts they are still showing 2.1.1.

This is a pretty critical update as the source files of 2.1.1 have been hacked allowing the hacker to execute php on every install of Wordpress... well I think thats the basis of it - read the link above to be sure.

Yeah it was a short hack though because version 2.1.2 came out a few days after which tells everyone to quickly upgrade so the hack won't cause them any harm.
