Authorization Bypass in OpenMage Magento-LTS via RSS Feed

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 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.

Executive Summary

OpenMage Magento-LTS before versions 20.18.2 and 21.0.0-beta1 to 21.0.0-beta3 has an authorization bypass in the /rss/order/status feed. The vulnerability allows unauthenticated attackers to forge unsigned Base64-encoded JSON keys using sequential order, increment, and customer IDs to access sensitive order details of other customers when the order-status RSS feature is enabled.

Detection Guidance

Check if the order-status RSS feed is enabled in OpenMage Magento-LTS. Inspect network traffic for requests to /rss/order/status. Look for unsigned Base64-encoded JSON in URLs containing order, increment, or customer IDs.

Impact Analysis

If you are a customer using OpenMage Magento-LTS with the affected versions and the order-status RSS feature enabled, attackers could exploit this to view your order details such as items, prices, totals, and status comments without authentication. This exposes personal and transactional data.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing personally identifiable information (PII) and protected health information (PHI) without authorization. It violates data protection principles requiring secure access controls and confidentiality of sensitive data.

Mitigation Strategies

Upgrade OpenMage Magento-LTS to version 20.18.2 or later, or 21.0.0-beta3 or later. Disable the order-status RSS feed if not required. Ensure proper access controls are enforced for sensitive data.
