The Return Refund and Exchange For WooCommerce – Return Management System, RMA Exchange, Wallet And Cancel Order Features plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.4.5 via the 'attachment' directory. This makes it possible for unauthenticated attackers to extract sensitive data stored insecurely in the /wp-content/attachment directory which can contain file attachments for order refunds.
