CVE-2026-25525 — OpenMage LTS has Path Traversal Filter Bypass in Dataflow Module

Description (CNA)

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 Dataflow module in OpenMage LTS uses a weak blacklist filter (`str_replace('../', '', $input)`) to prevent path traversal attacks. This filter can be bypassed using patterns like `..././` or `....//`, which after the replacement still result in `../`. An authenticated administrator can exploit this to read arbitrary files from the server filesystem. Version 20.17.0 patches the issue.
