    I tried to get nrepl to accept http requests once and I couldn't make it validate anything. (But of course I'd love to see someone manage to do it...)

    I don't think this is the same vulnerability. You don't even need to rebind DNS to do it, I believe: just make an XmlHTTPRequest. Your GET is considered code. The browser will get …

    It's not only a DNS rebind attack. I'm pretty sure in this case even a GET could get rce , so you don't even need to check the cors headers. You can just XHR.

    fwiw, stateless light switches are nice in that you can have many light switches controlling the same light. Not saying they're perfect but they have advantages.
