Widgets for Social Photo Feed <= 1.8 - Missing Authentication to Unauthenticated Plugin Settings Access/Update via trustindex_feed_hook_instagram REST API endpoints

The Widgets for Social Photo Feed plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the '/trustindex_feed_hook_instagram/troubleshooting' and '/trustindex_feed_hook_instagram/submit-data' REST API endpoints in all versions up to, and including, 1.8. This makes it possible for unauthenticated attackers to access and update plugin settings.
