Is this vulnerability remotely exploitable over the public internet?

Not by default. Exploitation requires the ability to invoke Gateway-related tools with a controllable `gatewayUrl`. In typical deployments, that capability is restricted to authenticated operators, trusted automation, or specifically provisioned environments. It becomes more exposed if a deployment allows less-trusted or external users to trigger these tool calls.

What level of access does an attacker need to abuse this issue?

The attacker must be able to supply or influence `gatewayUrl` for a tool invocation path that flows into the Gateway WebSocket client. This usually means having operator-level access, automation control, or equivalent permissions in the OpenClaw environment. Without such access, arbitrary internet users cannot normally exploit the issue.

What is the safest general fix pattern?

The most robust fix is to eliminate or heavily restrict dynamic endpoint selection: the Gateway client should connect only to predefined, configuration-driven endpoints or a tightly controlled allowlist. Any remaining URL parameters should undergo strict validation for scheme, host, port, and path, rejecting values that do not exactly match expected patterns.
