CVE-2026-42148 Details
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.
A command injection vulnerability has been identified in Coolify versions prior to 4.0.0-beta.474. The issue arises in the buildHelperImage method of the Livewire Settings component, where a Docker build command is created using the dev_helper_version input without proper shell escaping. This flaw allows an attacker to execute arbitrary commands on the server by injecting malicious payloads into the version string, particularly in a development environment where the vulnerability can be exploited.
Users are advised to update to Coolify version 4.0.0-beta.474 or later. For those unable to update, it is recommended to manually validate and escape the dev_helper_version input to prevent command injection.
