Another day, another WordPress security bug. Matt Mullenweg has released Wordpress 2.3.3 an open source (GPL) blog engine based on PHP and MySQL. "If you have registration enabled a flaw was found in the XML-RPC implementation such that a specially crafted request would allow a user to edit posts of other users on that blog. In addition to fixing this security flaw, 2.3.3 fixes a few minor bugs." All users should upgrade.
