CORS prevents the JS from seeing the result but it doesn't prevent the sending of the request. This is one of the reasons my internal network is not 192.168.1.

  > This is one of the reasons my internal network is not 192.168.1.1/24 and the router is not 192.168.1.1. Do you also disable WebRTC on all clients on your network? An attacker (or script) may be foiled by your non-standard gateway network, but your work in obfuscating the router is wasted if they can get at your client IP address.

  Doesn't CORS generally send an OPTION request first to see if the target site even allows the requests, thus preventing this? That's what I've seen when trying to work around browser CORS limitations.

    only for ajax requests that are not "simple", that is requests that cannot be sent w/out JavaScript. The sending of this OPTIONS request is referred to as a pre-flight.

    You can also just do a normal form post request into an invisible iframe that is generated by the attacker's javascript.
