Is this vulnerability remotely exploitable?

Yes, if the sandbox noVNC helper route is exposed over a network and not protected by additional network-layer controls, a remote attacker who can reach the endpoint may exploit it without valid credentials.

What level of access does an attacker need?

The primary requirement is network-level access to the affected OpenClaw instance and the ability to send requests to the noVNC helper route. No prior application authentication is needed if the missing authorization condition exists as described.

What is the safest general fix pattern?

The safest pattern is to enforce mandatory, centralized authorization checks on all helper routes dealing with session management or credentials. Every request to the noVNC helper route should verify the caller's identity and confirm that they are allowed to access the specific interactive browser session referenced.
