Subscriber email disclosure via unauthenticated AJAX action

Missing authentication in Smart Popup by Supsystic before 1.10.9 allows remote attackers to disclose subscriber email addresses. The public getListForTbl WordPress AJAX action accepts a subscription-list request and returns subscriber records without authenticating or authorizing the caller.
