Paymattic < 4.6.26 - Unauthenticated Payment Bypass via Unbound Stripe PaymentIntent

Published Sep 28, 2026 · Updated Sep 28, 2026 · Assigned by WPScan

Description

The Paymattic WordPress plugin from 4.6.20 before 4.6.26 does not verify that a confirmed Stripe payment belongs to the order it is applied to, allowing unauthenticated users to mark an arbitrary pending order as paid by confirming a smaller payment of their own against it.
