## Overview

The Sifalo Pay  WordPress plugin before 2.5.3 does not verify that a payment transaction identifier belongs to the order it is confirming, nor that the requester owns that order, allowing unauthenticated attackers holding one valid transaction identifier from a payment of their own to mark arbitrary pending orders as paid.
