Upgrade or else? - Wordpress 2.2.2 Security Issue
(3)
Even though I agree with Dougal's point that security outweighs themes or plugins you don't have to upgrade to 2.5, just upgrade to 2.2.3. And just because wordpress.org doesn't link to the 2.2.3 version doesn't mean it's absolutly necesary for you to risk your peice of mind. Just check the revision log for all the changes from 2.2.3 branch and update the files manually. You can get the files individually or the entire released zipped from the wordpress trac.
With that said, you do have to upgrade...now!SHARETHIS.addEntry({ title: "Upgrade or else? - Wordpress 2.2.2 Security Issue", url: "http://dancameron.org/general/upgrade-or-else-wordpress-222-security-issue" });
