Smart Forms <= 2.6.99 - Missing Authorization to Authenticated (Subscriber+) Campaign Data Exposure

The Smart Forms plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'rednao_smart_forms_get_campaigns' AJAX action in all versions up to, and including, 2.6.99. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve donation campaign data including campaign IDs and names.
