Technical 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 the Database Backup functionality allows users with application/service management permissions to execute arbitrary commands as root on managed servers. Database names used in backup operations are passed directly to shell commands without sanitization, enabling full remote code execution. Version 4.0.0-beta.451 fixes the issue.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
