Advisory

Source description from Wordfence Intelligence, credited to Lucio Sá.

The Hostinger plugin for WordPress is vulnerable to unauthorized plugin settings update due to a missing capability check on the function publish_website in all versions up to, and including, 1.9.7. This makes it possible for unauthenticated attackers to enable and disable maintenance mode.
