# OpenMage magento-lts: free payment method accepts unpaid full-price orders via API

Link for people: https://infrastack.ai/live/CVE-2026-128032 (this .md is for agents)

OpenMage magento-lts accepts the free payment method on orders whose total is not zero, because the zero-total check runs only when payment data is imported. An API user with cart permissions can place an unpaid full-price order.

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

## How to check

- Check the installed magento-lts version: `composer show openmage/magento-lts` or the version shown in the admin footer.
- Confirm whether API users have cart permissions (cart_payment.method, cart_coupon.remove, cart.order) in the API role configuration.

## Fix

- `magento-lts` before `20.18.2` (20.x line)
- `magento-lts` `21.0.0-beta1` before `21.0.0-beta3` (21.x beta line)

## From the sources

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 accepts the free (No Payment Information Required) payment method on orders with a non-zero total because the zero-total check runs only when payment data is imported. An API user with cart permissions can select free via cart_payment.method while the total is zero, raise it with cart_coupon.remove, and submit cart.order to place an unpaid full-price order.
