Advisory

Source description from Wordfence Intelligence, credited to apple502j.

The Print My Blog WordPress Plugin before 3.4.2 does not enforce nonce (CSRF) checks, which allows attackers to make logged in administrators deactivate the Print My Blog plugin and delete all saved data for that plugin by tricking them to open a malicious link.
