description

UPI QR Code Payment Gateway for WordPress through 1.4.3 can accept payment confirmations without properly tying them to the relevant order and customer. An unauthenticated attacker may be able to cause arbitrary orders to be recorded as paid without completing payment when the confirmation functionality is exposed.

mitigation

Disable or remove the affected plugin until the vendor provides an update. If operationally possible, restrict public access to its payment-confirmation functionality and manually verify order payments.
