CVE-2026-42143: 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.471, user-controlled persistent volume names are interpolated into shell commands executed on managed servers without escaping or validation, allowing an authenticated member to inject shell metacharacters and execute commands as root when volume operations are triggered. This issue appears to be fixed in version 4.0.0-beta.471.
AI Analysis
Technical Summary
CVE-2026-42143 is an OS command injection vulnerability in Coolify, an open-source server and application management tool. Before version 4.0.0-beta.471, user-controlled persistent volume names are directly interpolated into shell commands without proper escaping or validation. This allows an authenticated user to inject shell metacharacters and execute arbitrary commands with root privileges when volume operations are performed. The vulnerability is resolved in version 4.0.0-beta.471.
Potential Impact
An authenticated user can execute arbitrary commands as root on the managed servers, leading to full system compromise including confidentiality, integrity, and availability impacts. This can result in unauthorized access, data manipulation, or service disruption.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.471 or later, where this vulnerability is fixed. No other remediation or temporary fixes are indicated. Ensure that only trusted users have authenticated access to the system until patched.
