How broadly exploitable is this vulnerability?

Any attacker who can obtain a low-privileged Coolify account on an affected instance may be able to retrieve the root SSH private key and use it to log in as root, assuming the key is still trusted by the server or other systems.

What level of access does an attacker need to exploit this?

The attacker typically needs authenticated, low-privilege access to the Coolify interface or API—such as a regular user account. No direct shell or file-system access is required if the key is visible through the application.

What is the safest general fix pattern?

The safest approach is to redesign how secrets are handled: treat SSH private keys as non-retrievable secrets, restrict any secret-handling functions to trusted administrative paths, and avoid using root-level keys where possible. Keys that may have been exposed should be rotated and their trust revoked.
