⚠️ Risk & Real-World Impact
Worst Case
Full root-level remote code execution on all managed servers, allowing complete system compromise, data exfiltration, and lateral movement across infrastructure.
Likely Case
Privileged authenticated users can execute arbitrary commands on managed servers, potentially compromising databases, applications, and underlying infrastructure.
If Mitigated
With proper access controls and network segmentation, impact is limited to specific managed servers accessible to the compromised user account.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained. Public proof-of-concept exists in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.0.0-beta.451
Vendor Advisory: https://github.com/coollabsio/coolify/security/advisories/GHSA-q33h-22xm-4cgh
Restart Required: Yes
Instructions:
1. Backup your Coolify configuration and data. 2. Update to version 4.0.0-beta.451 or later using: docker pull coollabsio/coolify:latest. 3. Restart the Coolify container. 4. Verify the update completed successfully.
🔧 Temporary Workarounds
Disable Database Import Functionality
linuxTemporarily disable or restrict access to the Database Import feature in Coolify until patching is possible.
Restrict User Permissions
allReview and reduce application/service management permissions for users who don't absolutely require them.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Coolify instances from critical infrastructure
- Enable detailed logging and monitoring for all database import operations and shell command execution
🔍 How to Verify
Check if Vulnerable:
Check if your Coolify version is below 4.0.0-beta.451. Review user permissions to identify accounts with application/service management access.
Check Version:
docker exec coolify cat /app/package.json | grep version
Verify Fix Applied:
Confirm version is 4.0.0-beta.451 or higher and test that database import functionality properly sanitizes input.
📡 Detection & Monitoring
Log Indicators:
- Unusual database import operations
- Shell command execution from Coolify process
- Database names containing shell metacharacters
Network Indicators:
- Unexpected outbound connections from Coolify server
- SSH or remote access attempts from Coolify to managed servers
