SCA: security update for openmage/magento-lts (GHSA-3j5q-7q7h-2hhv)

high Tenable Self-Hosted Container Security Plugin ID 440684

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the
 Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to
 version 20.17.0, the product custom option file upload in OpenMage LTS uses an incomplete blocklist
 (`forbidden_extensions = php,exe`) to prevent dangerous file uploads. This blocklist can be trivially
 bypassed by using alternative PHP-executable extensions such as `.phtml`, `.phar`, `.php3`, `.php4`,
 `.php5`, `.php7`, and `.pht`. Files are stored in the publicly accessible `media/custom_options/quote/`
 directory, which lacks server-side execution restrictions for some configurations, enabling Remote Code
 Execution if this directory is not explicitly denied script execution. Version 20.17.0 patches the issue.
 (CVE-2026-40488)

Solution

Update the openmage/magento-lts library and its related packages to version 20.17.0 or later.
