high Tenable Self-Hosted Container Security Plugin ID 440705

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, PHP functions such as `getimagesize()`, `file_exists()`, and `is_readable()` can trigger
deserialization when processing `phar://` stream wrapper paths. OpenMage LTS uses these functions with
potentially controllable file paths during image validation and media handling. An attacker who can upload
a malicious phar file (disguised as an image) and trigger one of these functions with a `phar://` path can
achieve arbitrary code execution. Version 20.17.0 patches the issue. (CVE-2026-25524)

Solution

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