Unauthenticated order manipulation via unchecked failure webhook
Published Oct 15, 2026 · Updated Oct 15, 2026
Webhook forgery in Rede Itaú for WooCommerce before 5.5.3 allows remote attackers to alter order statuses without authentication. The 3D Secure failure webhook skips its authenticity check when the tid parameter is absent, accepting an unverified callback to update an order. Exploitation requires access to the affected webhook and affects order state, including already paid or completed orders, rather than proving that payment occurred.
