CVE-2026-42143: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coollabsio coolify
CVE-2026-42143 is an OS command injection vulnerability in coollabsio's Coolify, an open-source server and application management tool. Versions prior to 4.0.0-beta.471 allow authenticated users to inject shell commands via user-controlled persistent volume names, which are not properly escaped or validated. This can lead to arbitrary command execution with root privileges when volume operations are performed. The issue is reportedly fixed in version 4.0.0-beta.471.
AI Analysis
Technical Summary
Coolify versions before 4.0.0-beta.471 improperly handle user-controlled persistent volume names by interpolating them directly into shell commands executed on managed servers without escaping or validation. This allows an authenticated member to inject shell metacharacters and execute arbitrary commands as root during volume operations. The vulnerability is classified as CWE-78 (OS Command Injection) and has a CVSS 3.1 base score of 8.8, indicating high severity. The fix is included starting from version 4.0.0-beta.471.
Potential Impact
An authenticated user can exploit this vulnerability to execute arbitrary OS commands with root privileges on the managed servers. This can lead to full system compromise, including confidentiality, integrity, and availability impacts as reflected by the high CVSS score (8.8).
Mitigation Recommendations
Upgrade to version 4.0.0-beta.471 or later, where this vulnerability is fixed. Since no official patch or remediation level is explicitly stated beyond the fixed version, applying this upgrade is the recommended remediation. No additional mitigations are specified.
