Airwallex Online Payments Gateway < 1.36.0 - Unauthenticated Payment Bypass via Forged Webhook

Published Oct 8, 2026 · Updated Oct 8, 2026 · Assigned by WPScan

Description

The Airwallex Online Payments Gateway WordPress plugin before 1.36.0 does not verify that an incoming payment notification genuinely comes from the payment provider when no webhook secret has been configured, allowing unauthenticated attackers to forge one and mark orders as paid without paying.
