The CallbackKiller service widget plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the cbk_save() function in all versions up to, and including, 1.2. This makes it possible for unauthenticated attackers to modify the plugin's site ID settings via the 'cbk_save_v1' AJAX action.
