Constant Contact Forms <= 2.0.2 - Missing Authorization via constant_contact_privacy_ajax_handler

The Constant Contact Forms plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the constant_contact_privacy_ajax_handler function in versions up to, and including, 2.0.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify the plugin's privacy agreement settings.
