01What is this vulnerability?

Magento LTS is the official OpenMage LTS codebase. Guest orders may be viewed without authentication using a "guest-view" cookie which contains the order's "protect_code". This code is 6 hexadecimal characters which is arguably not enough to prevent a brute-force attack. Exposing each order would require a separate brute force attack. This issue has been patched in versions 19.5.1 and 20.1.1.

02Affected products

Vendor	Product	Versions
OpenMage	magento	lts — <= 19.5.0, >= 20.0.0, <= 20.1.0

03Active exploitation status

Not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog. EPSS is the best forward-looking signal — see the EPSS row above.

04Recommended remediation

• Patch to a fixed version listed in the vendor advisory (see references below).
• Mitigate with WAF rules, network egress filters, or feature flags where the patch is not yet available.
• Hunt historical logs for exploitation indicators — see Detection signatures below.
