Description

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.

Affected products

• Thelia: from 2.6.2 before 3.1.5; from 3.2.0 before 3.2.4 — fixed in 3.1.5, 3.2.4

How to fix

Upgrade to a fixed version: Thelia 3.1.5, 3.2.4. Check the vendor advisory for mitigations.
