For everyone out there that is using WordPress is extremely advised to update to the latest version which can be done manually or by using the Admin Interface.
Version 3.0.4 of WordPress, available immediately through the update page in your dashboard or for download here, is a very important update to apply to your sites as soon as possible because it fixes a core security bug in our HTML sanitation library, called KSES. I would rate this release as “critical.”
