The Facebook Chat Plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the wp_ajax_update_options function in versions up to, and including, 1.5. This flaw makes it possible for low-level authenticated attackers to connect their own Facebook Messenger account to any site running the vulnerable plugin and engage in chats with site visitors on affected sites.
