Description

CVE-2026-128052 is an incorrect authorization vulnerability in OpenMage magento-lts before versions 20.19.0 and 21.0.0-beta3. The flaw exists in the template filter's {{layout}} directive, which allows rendering of arbitrary layout handles without enforcing the admin/block whitelist that applies to the {{block}} directive. Administrators with permissions to edit email, CMS, widget, or newsletter content can exploit this to embed {{layout}} with arbitrary handles, potentially rendering disallowed blocks and disclosing limited information.
