CVE-2026-42148

Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, the buildHelperImage method in app/Livewire/Settings/Index.php constructs a Docker build command using the dev_helper_version field without shell escaping, allowing an attacker who can set the helper version and trigger the helper image build in a development environment to execute arbitrary commands on the server. This issue is fixed in version 4.0.0-beta.474.
