Advisory
Source description from Wordfence Intelligence, credited to Jerome Bruandet.
The 404 to 301 plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on the open_redirect & save_redirect functions in versions up to, and including, 3.0.7. This makes it possible for authenticated attackers to view, create and edit redirections.
