Admin side data storage for Contact Form 7 <= 1.1.1 - Missing Authorization to Unauthenticated Bookmark Status Alteration

Description The Admin side data storage for Contact Form 7 plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the zt_dcfcf_change_bookmark() function in all versions up to, and including, 1.1.1. This makes it possible for unauthenticated attackers to alter bookmark statuses.
