Unauthorized Access to Configuration Secrets in OpenMage Magento-LTS

Publication date: 2026-11-13

Last updated on: 2026-11-13

Assigner: VulnCheck

Description
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.

Executive Summary

This vulnerability in OpenMage Magento-LTS allows restricted administrators to read decrypted configuration secrets via email templates. The issue occurs because the getConfig directive's encrypted-path check fails to block config.xml-declared paths, case variants of the method name, and parent paths. Attackers with Transactional Emails access can preview crafted templates to expose sensitive credentials like PayPal API keys or payment gateway tokens.

Detection Guidance

Check OpenMage Magento-LTS versions before 20.18.2 or 21.0.0-beta1. Review email template directives for store.getConfig usage with encrypted paths like paypal_api_key. Test case-insensitive method calls (getconfig, GETCONFIG) and parent path access.

Impact Analysis

The vulnerability allows unauthorized access to sensitive data such as PayPal API keys, payment gateway tokens, and carrier passwords. Even administrators with limited permissions can exploit this to leak decrypted secrets by previewing malicious email templates. This could lead to financial fraud, data breaches, or unauthorized system access if credentials are compromised.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR (data protection) and HIPAA (healthcare data privacy) by exposing sensitive credentials and configuration secrets. Unauthorized access to payment or user data may result in regulatory fines, legal liabilities, and reputational damage due to breaches of confidentiality requirements.

Mitigation Strategies

Update OpenMage Magento-LTS to version 20.18.2 or later, or 21.0.0-beta3 or later. Rotate all exposed credentials (PayPal API keys, payment gateway tokens, carrier passwords). Restrict Transactional Emails access to trusted administrators.
