CVE-2026-19436Network attack vector

Unauthenticated store-credit inflation via unreconciled checkout value

Published Sep 10, 2026 · Updated Sep 10, 2026

Improper access control in Ultimate Gift Cards for WooCommerce before 3.2.10 allows remote attackers to inflate store credit at checkout. The checkout workflow issues a gift-card coupon from its face value without reconciling that value against the discounted amount actually collected. No account is required; a discounted gift-card purchase yields redeemable store credit exceeding the payment, causing direct merchant loss.
