AI-suggested
- Immediately upgrade all Coolify instances to version 4.0.0-beta.420.7 or later to apply the official patch.
- Restrict project creation and update permissions to trusted, high-privileged users only, minimizing the risk of malicious Docker Compose injection.
- Implement strict input validation and sanitization on any user-supplied configuration data related to Docker Compose files.
- Monitor Docker Compose configurations and deployment workflows for unauthorized or suspicious changes using file integrity monitoring and audit logging.
- Employ container runtime security tools that can detect and prevent host filesystem mounts or privilege escalations.
- Conduct regular security assessments and penetration tests focusing on container escape vectors.
- Isolate Coolify management interfaces behind strong network controls and multi-factor authentication to reduce exposure.
- Educate administrators and developers about the risks of improper configuration and the importance of applying security patches promptly.
Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to version 4.0.0-beta.420.7, a Remote Code Execution (RCE)*vulnerability exists in Coolify's application deployment workflow. This flaw allows a low-privileged member to inject arbitrary Docker Compose directives during project creation or updates. By defining a malicious service that mounts the host filesystem, an attacker can achieve root-level command execution on the host OS, completely bypassing container isolation. Version 4.0.0-beta.420.7 contains a patch for the issue.
