Popup – MailChimp, GetResponse and ActiveCampaign Intergrations <= 3.2.6 - Missing Authorization to Unauthenticated DB Table Truncation

The Popup – MailChimp, GetResponse and ActiveCampaign Intergrations plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'upc_delete_db_data' AJAX action in all versions up to, and including, 3.2.6. This makes it possible for unauthenticated attackers to delete the DB data for the plugin.
