CVE-2023-51502Network attack vector

Unauthenticated payment modification via unchecked payment key

Published Jan 5, 2024 · Updated Apr 28, 2026

IDOR in WooCommerce Stripe Payment Gateway 7.6.1 and earlier allows remote attackers to update payments belonging to other orders. The update_payment_intent_ajax handler accepts a user-controlled payment key without validating that the referenced payment belongs to the associated order. No authentication or user interaction is required, and exploitation changes payment data rather than merely disclosing it.
