Advisory

Source description from Wordfence Intelligence.

WordPress 3.1 before 3.1.3 and 3.2 before Beta 2 does not prevent rendering for (1) admin or (2) login pages inside a frame in a third-party HTML document, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site.
