CVE-2025-64420Network attack vector

Root host takeover via exposed SSH key

Published Jan 5, 2026 · Updated Jan 5, 2026

Credential exposure in coolLabs Coolify 4.0.0-beta.434 and earlier allows remote authenticated users to obtain the host root SSH key. The server-management view exposes the Coolify host's stored private key to ordinary member accounts without restricting the credential to administrators. A member account is sufficient to authenticate over SSH as root and gain full control of the self-hosted Linux server.
