CVE-2010-4257: SQL Injection
First published: Thu Dec 02 2010(Updated: )
An improper input sanitization flaw was found in the way Wordpress performed trackbacks (a way to notify a website when an entry that references it is published) maintainance. A remote attacker, with Author-level privilege could use this flaw to conduct SQL injection attacks (gain further access to the site, which should be otherwise prohibited).

Will post a copy of upstream patch here.
