WordPress.org has just released a critical update for their blogging software. Version 2.1.2 fixes malicious modifications that were introduced by a hacker who somehow got access to the download server. Or as Matt puts it:

Long story short: If you downloaded WordPress 2.1.1 within the past 3-4 days, your files may include a security exploit that was added by a cracker, and you should upgrade all of your files to 2.1.2 immediately.

I’ve just finished upgrading my blogs, and you should to. Spread the word!
