CVE-2026-59547Network attack vector

Underpaid order completion via unreconciled PayPal payment

Published Jul 23, 2026 · Updated Jul 23, 2026

Broken access control in Payment Gateway for PayPal on WooCommerce 9.1.4 and earlier allows remote attackers to complete underpaid orders. The checkout capture path accepts an approved PayPal order without reconciling its embedded order identifier, amount, and currency against the WooCommerce order. An unauthenticated shopper can substitute a different PayPal payment, including a lower-value one, and cause the store to mark the target order paid.
