# OpenMage magento-lts: restricted admins can read decrypted payment and carrier secrets

Link for people: https://infrastack.ai/live/CVE-2026-128048 (this .md is for agents)

OpenMage magento-lts lets an administrator with Transactional Emails access preview a crafted email template that exposes decrypted configuration secrets. The exposed values include PayPal, payment gateway, and carrier credentials.

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

## How to check

- Check the installed magento-lts version in composer.json or the OpenMage package lock; compare against `20.18.2` and `21.0.0-beta3`.
- Review which admin roles have Transactional Emails access.

## Fix

- magento-lts: move to `20.18.2` or later on the 20.x line, or `21.0.0-beta3` or later on the 21.0 beta line.

## From the sources

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 lets restricted administrators read decrypted configuration secrets because the store.getConfig email template directive's encrypted-path check missed config.xml-declared paths, case variants of the getConfig method name, and parent paths. Administrators with Transactional Emails access can preview a crafted template to expose PayPal, payment gateway, and carrier credentials.
