AI-suggested
To mitigate CVE-2025-66211, organizations should immediately upgrade Coolify to version 4.0.0-beta.451 or later, where the vulnerability is patched. Until the upgrade is applied, restrict application and service management permissions strictly to trusted and vetted users to reduce the attack surface. Implement robust access controls and monitor for unusual command execution or privilege escalation activities on managed servers. Employ network segmentation to isolate management interfaces and limit exposure to untrusted networks. Additionally, review and sanitize any user-supplied input related to PostgreSQL initialization scripts or other shell-invoked parameters. Consider deploying runtime application self-protection (RASP) or host-based intrusion detection systems (HIDS) to detect and block suspicious command injection attempts. Regularly audit Coolify configurations and logs for signs of exploitation. Finally, educate administrators about the risks of command injection vulnerabilities and the importance of applying security updates promptly.
Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to version 4.0.0-beta.451, an authenticated command injection vulnerability in PostgreSQL Init Script Filename handling allows users with application/service management permissions to execute arbitrary commands as root on managed servers. PostgreSQL initialization script filenames are passed to shell commands without proper validation, enabling full remote code execution. Version 4.0.0-beta.451 fixes the issue.
