Security vulnerability in `tunnel-agent`

You may already be aware of this issue, but I figured I'd post it here anyway, just in case I'm wrong. (I don't see it already posted.)

When running an `npm audit` on my Laravel project, I get several Moderate security vulnerabilities related to the `tunnel-agent` dependency. It seems there _is_ a patch available, but it requires that you update `caw` so that it will use `tunnel-agent` version `>=0.6.0`:

```

```

Start by inspecting caw's dependency declarations and running the reported npm audit path for tunnel-agent. Confirm that the dependency resolves to version 0.6.0 or newer, then verify that the vulnerability is no longer reported.
