CVE-2026-128031

Description

OpenMage magento-lts before 20.18.2 and 21.0.0-beta1 before 21.0.0-beta3 contains an incorrect authorization vulnerability because admin controllers' _isAllowed() checks fall back to, or only check, parent ACL resources instead of finer per-action permissions. Authenticated restricted administrators can mass cancel or hold orders, rewrite order shipping addresses, export customer report data, or create REST roles despite their role denying those permissions.
