Is this vulnerability remotely exploitable over the internet?

It can be, depending on how the host loopback interface is exposed. While the service is bound to localhost, attackers may gain access via local accounts, SSH port forwarding, container network misconfigurations, or proxies that expose loopback-bound ports to remote clients.

Does an attacker need valid OpenClaw credentials to exploit this?

Not necessarily. Exploitation does not require OpenClaw-level authentication if the attacker can directly reach the noVNC endpoint on the loopback interface. The core problem is that the VNC observer interface itself does not enforce authentication.

What is the safest general fix pattern?

Enforce strong authentication for any VNC/noVNC observer interface and place it behind a controlled access layer, such as an authenticated reverse proxy. In parallel, avoid exposing the service on interfaces that can be reached by untrusted users, and consider disabling the feature when not strictly required.
