# Thelia: coupon usage limits bypassed through pay-later and cancelled orders

Thelia, an open-source e-commerce platform, counts coupon usage only when orders are paid, so a logged-in customer can place several pay-later orders while one use remains. Cancelling paid orders also raises the coupon's max_usage, letting the customer keep getting unlimited discounts.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Thelia version in the project's composer.json or the admin footer; versions below `3.1.5` or `3.2.x` below `3.2.4` are affected.
- Review coupons with a usage limit for unusual order counts from single customers.

## Fix

- Upgrade Thelia to `3.1.5` or later on the 3.1 line, or to `3.2.4` or later on the 3.2 line.

## From the sources

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.
