# OpenMage Magento-LTS: forged RSS keys expose other customers' order details

Link for people: https://infrastack.ai/live/CVE-2026-128045 (this .md is for agents)

OpenMage Magento-LTS builds its order-status RSS feed URL key from unsigned Base64 JSON of order and customer ids. An unauthenticated attacker can forge keys from sequential ids and read other customers' names, items, prices, totals and status comments when order-status RSS is enabled.

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

## How to check

- Check the installed version of Magento-LTS (OpenMage) against the fixed versions below.
- Check whether order-status RSS is enabled in the store configuration for the RSS order status feed.
- Check whether requests to `/rss/order/status` are reachable from the internet.

## Fix

- Magento-LTS (OpenMage) before `20.18.2`: move to `20.18.2` or later.
- 21.x before `21.0.0-beta3`: move to `21.0.0-beta3` or later.

## From the sources

OpenMage Magento-LTS before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains an authorization bypass in the /rss/order/status feed because its URL key is unsigned Base64-encoded JSON of the order, increment, and customer ids. Unauthenticated attackers can forge keys from enumerated sequential ids to read other customers' names, items, prices, totals, and status comments when order-status RSS is enabled.
