Order Attachments for WooCommerce <= 2.5.1 is vulnerable to Unauthenticated Sensitive Information Exposure Through Unprotected Directory vulnerability

The Order Attachments for WooCommerce plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.5.1 via the 'uploads' directory. This makes it possible for unauthenticated attackers to extract sensitive data stored insecurely in the /wp-content/uploads directory which can contain file attachments added to orders.
