Is Turbo.net Extension safe?

Low risk

Turbo.net Extension forwards every browser navigation URL to a locally installed Turbo.net sandman process via WebSocket.

The extension intercepts all top-level page navigations and sends each URL to a locally running sandman process at ws://127.0.0.1:{port}/sandman. A postMessage bridge in the content script also allows pages hosting a Turbo Server deployment to relay arbitrary WebSocket commands to the local sandman, using the static public extension ID as the only gate. This means any cross-site scripting flaw on a Turbo Server page could be used to send commands to the sandman at any localhost port.
