CVE-2023-41879: Openmage Magento

High severity, CVSS 7.5. EPSS: 1.3% chance of exploitation in the next 30 days.

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.

Affected products

• Openmage Magento: before 19.5.1 (fixed in 19.5.1); from 20.0.0, before 20.1.1 (fixed in 20.1.1)
