What is CVE-2026-128048?

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.
