Is this vulnerability remotely exploitable over the internet?

It is primarily a local attack surface. Exploitation generally requires the attacker to run code or send network requests from the same host or local environment where the sandbox browser bridge server is listening. However, if the bridge is inadvertently exposed beyond localhost, the risk can extend to adjacent network attackers.

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

The attacker needs local-level access sufficient to communicate with the bridge server (e.g., a local user account, malware running on the machine, or another process able to open TCP connections to the bridge). No authentication to the OpenClaw gateway is required.

What is the safest general fix pattern?

Enforce robust authentication and authorization for all browser bridge endpoints that perform sensitive actions. Introduce an explicit security boundary, require gateway-issued or otherwise validated credentials, and ensure that high-privilege operations cannot be invoked without passing these checks.
