Well, from the first post:

Our engineering staff was quickly called in and was able to mass undo these changes fairly quickly. The event in total lasted approximately an hour. In the next few hours, Wikia Staff will try to identify how the testing account was compromised and make immediate changes to make sure it won’t happen again. We have no reasons to believe any other accounts were compromised or that there was an attack vector that involved Cross-Site Scripting or other forms of hacking.

I think they're working on that.
