## Summary

The UniPAY Payment Gateway plugin for WooCommerce, a WordPress add-on, has a flaw that lets an unauthenticated attacker request an order by ID and receive its secret order key along with customers' names, email addresses, phone numbers, and addresses. The attacker can reach it without logging in by supplying arbitrary order IDs to the order-received redirect, which lets them enumerate orders and collect personal data.
