Technical details

This access bypass vulnerability exists in the Commerce PayPal module's transaction validation logic, specifically when using the Payflow Link payment gateway. The module fails to sufficiently validate payment transaction results in certain circumstances, permitting an attacker to forge a successful payment status without actually completing payment. The vulnerability is exploitable by any unauthenticated user interacting with the Payflow Link gateway—no special authentication or complex prerequisites are required. An attacker can leverage this to place orders and mark them as paid without payment, resulting in direct financial fraud. Patches are available in versions 2.1.3 and 8.x-1.12, released on 12 August 2026.
