Advisory

Source description from Wordfence Intelligence, credited to rootetsy.

The Hybrid Composer plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the hc_ajax_save_option function in versions up to, and including, 1.4.6. This makes it possible for unauthenticated attackers to fully access and modify administrative settings/actions.
