A upgrade described as critical has been released for websites using WordPress. The WordPress team released the critical upgrade “WordPress 3.0.4” as a security update for a XSS vulnerability which may have allowed malicious attackers to revoke your access to the admin dashboard.

On the wordpress blog, Matt Mullenweg apologetically stated that an update during the holidays is no fun, but this one is worth putting down the eggnog for!

For both wordpress users and other, it is always a good time to remind users to make a manual backup of your websites. Most web hosting companies perform some form of nightly backup, but as many of the reviews on HostJury will attest, this is designed for the web hosts internal use in the event of a total loss of data. Do not hesitate to ask your webhost how to perform a manual backup if you any questions... eggnog or no eggnog!
