Thelia before 3.1.5 and 3.2.x before 3.2.4 contains a business logic vulnerability that allows authenticated customers to bypass coupon usage limits because usage is counted only when orders become paid. Attackers can place multiple pay-later orders while a usage remains, or cancel paid orders to inflate max_usage, gaining unlimited discounts.
