CVE-2026-119558
OpenCart through 4.1.0.4 Payment Bypass via Free Checkout Reward Points
OpenCart through 4.1.0.4 contains a business logic vulnerability that allows logged-in customers to place unpaid full-price orders by clearing reward points after selecting Free Checkout. Attackers can apply points, save Free Checkout, then submit zero points via reward.save so the confirm handler advances the order to Free Checkout status without payment.
