CVE-2026-34038: 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.469, an authenticated remote command injection vulnerability in application deployment handling allows users with application write permissions to achieve remote code execution and exfiltrate sensitive environment variables through deployment logs via fields such as dockerfile_location and deployment commands. This issue is fixed in version 4.0.0-beta.469.
AI Analysis
Technical Summary
CVE-2026-34038 is an OS command injection vulnerability (CWE-78) in Coolify before version 4.0.0-beta.469. It allows authenticated users with application write permissions to inject and execute arbitrary OS commands during application deployment by manipulating input fields like dockerfile_location and deployment commands. This can lead to remote code execution and leakage of sensitive environment variables via deployment logs. The vulnerability has a CVSS 3.1 score of 9.9, indicating critical severity. The issue is resolved in version 4.0.0-beta.469.
Potential Impact
Successful exploitation enables remote code execution with the privileges of the affected application, allowing attackers to run arbitrary OS commands. Additionally, attackers can exfiltrate sensitive environment variables through deployment logs, potentially exposing confidential data. This poses a critical risk to the confidentiality, integrity, and availability of affected systems.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.469 or later, where this vulnerability is fixed. Since this is an authenticated vulnerability requiring application write permissions, restricting access to trusted users can reduce risk until the patch is applied. Patch status is not explicitly stated in the vendor advisory, but the description confirms the issue is fixed in 4.0.0-beta.469.
