# OpenMage magento-lts: restricted admins bypass per-action permissions on orders and customers

Link for people: https://infrastack.ai/live/CVE-2026-128031 (this .md is for agents)

OpenMage magento-lts admin controllers check only parent access rules instead of per-action permissions. An authenticated restricted administrator can cancel or hold orders, rewrite shipping addresses, export customer data and create REST roles despite their role denying those actions.

_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.lock or the OpenMage package metadata against `20.18.2` and `21.0.0-beta3`
- Review admin roles that are restricted from order or customer actions, since those are the ones that can be bypassed

## Fix

- magento-lts `20.18.2` for the 20.x line
- magento-lts `21.0.0-beta3` for the 21.0.0 beta line

## From the sources

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains an incorrect authorization vulnerability because admin controllers' _isAllowed() checks fall back to, or only check, parent ACL resources instead of finer per-action permissions. Authenticated restricted administrators can mass cancel or hold orders, rewrite order shipping addresses, export customer report data, or create REST roles despite their role denying those permissions.
