# OpenMage magento-lts: RSS order feed exposes internal staff comments to customers

Link for people: https://infrastack.ai/live/CVE-2026-128033 (this .md is for agents)

OpenMage magento-lts omits the front-visibility filter on invoice, shipment and credit-memo comments in its order status RSS feed. A logged-in customer can read internal staff notes such as fraud-review and payment remarks for their own orders.

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

## Affected

- composer:magento-lts affected range not listed fixed no fixed version listed

## How to check

- Check the installed magento-lts version against the ranges below, for example in `composer.lock` or the `app/etc/local.xml` install.
- Confirm the RSS order status feed is reachable at `/rss/order/status` for logged-in customers.

## Fix

- Upgrade magento-lts to `20.18.2` on the 20.x line.

## From the sources

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains an information disclosure vulnerability in Mage_Rss_Model_Resource_Order::getAllCommentCollection(), which omits the is_visible_on_front filter for invoice, shipment and credit-memo comments. Authenticated customers can open the /rss/order/status feed for their order to read internal staff comments, such as fraud-review and payment notes.
