Unsafe ControlPath

warningChecked in the browserUNSAFE_CTRL_PATH

ControlPath does not uniquely identify host, port, and user.

Why it matters

Different SSH connections can collide and reuse the same control socket.

How to fix it

Replace the path with a compact hash such as ~/.ssh/control-%C, or include all three tokens %r@%h:%p. Keep the socket directory private and create it before connecting if you place sockets in a subdirectory.
