Summary
9remote is a remote-shell tool: its CLI launches an HTTP/WebSocket server and provisions a Cloudflare Quick Tunnel that exposes the host to the public internet at a 9remote.cc-fronted URL. Incoming WebSocket input messages are forwarded verbatim into a locally spawned PTY (bash/zsh on Unix, cmd.exe/powershell.exe on Windows) via pty.write(s.data) , after spawn(o.path, o.args,...) in the pty daemon. The server's router treats requests bearing the cf-connecting-ip header as remote-authorized. Access is gated by a short-lived (~30-minute) one-time pair key shown as a QR code; anyone who obtains that key over the tunnel obtains a full interactive shell on the host with the user's privileges. The package is invoked explicitly by the operator (bin entry, not lifecycle scripts or top-level require side effects), and the tunnel terminates at first-party infrastructure (9remote.cc / Cloudflare), so this is the advertised behavior of the tool rather than a covert channel — but the blast radius on any host where the CLI is run is full-host remote code execution behind a single short-lived key.
