A vulnerability/exploit has been found in Wordpress - a good many wordpress sites are being defaced by that big red exclamation point. It's kind of reminiscent of when NeverNoSanity took down all the phpBB based sites.... and people wonder why I call it turdpress. It doesn't have security holes QUITE as large as phpBB, but it's damned close. Combine that with the total manure most of the themes barf up for HTML and there's no reason any 'professional' website should even THINK about being based on it.
