I've just got a couple of hundred notifications that someone's scanning my site, appending 3.0.2.1 to every URL. I assume the reason behind this is WP's enqueue appends the version number to any scripts (in order to break cache when you need to). If anyone's still running WordPress 3.0.2.1, now would be a good time to update.
Not sure what the actual vulnerability is, because I don't append WP's version number and my WP is up to date, but Uncle Chris is looking out for you. Now run along and update.
