CVE-2026-42148: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coollabsio coolify
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.
AI Analysis
Technical Summary
CVE-2026-42148 describes an OS command injection vulnerability (CWE-78) in coollabsio's Coolify product. Specifically, in versions before 4.0.0-beta.474, the buildHelperImage method in app/Livewire/Settings/Index.php improperly uses the dev_helper_version field to build a Docker command without shell escaping. This allows an attacker who can control this field and trigger the build process in a development environment to execute arbitrary OS commands. The vulnerability is resolved in version 4.0.0-beta.474.
Potential Impact
Successful exploitation allows an attacker with high privileges and user interaction in a development environment to execute arbitrary commands on the server, potentially leading to limited confidentiality, integrity, and availability impacts. The CVSS score is 3.8 (low), reflecting the requirement for high privileges and user interaction.
Mitigation Recommendations
Upgrade to version 4.0.0-beta.474 or later where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Until upgrading, restrict access to development environments and the ability to set the dev_helper_version field to trusted users only.
