2Download Connector for 2DL Hosted Checkout <= 0.1.5 - Missing Authorization to Unauthenticated Sensitive Customer Subscription Data Exposure via 'ToDownload_email' Parameter

The 2Download Connector for 2DL Hosted Checkout plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 0.1.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to view arbitrary customers' subscription data including subscription status, product names, order IDs, purchase dates, and expiry dates.
