Smart Forms < 2.6.101 - Missing Authorization to Authenticated (Subscriber+) Campaign Data Exposure

Description

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, 2.6.100. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve donation campaign data including campaign IDs and names.
