[WEB SECURITY] Bypassing URL Authentication and Authorization with HTTP Verb Tampering

I don't exactly know why, but you're trying to blur the difference between "alerting the world when most of them are doing it wrong" and "knowing what the RFC says", which is fairly unimportant.
If this is a well known issue, please point me to the CWE ID or any other prior listing of this information? I'm not saying you didn't already have attack technique in your pocket, I'm saying that the world needed an alert.
Incidentally, if there is no prior art out there, and someone releases something, and you say "I knew about that before you did!!! And seeing it out on the Interweb makes me soooOO madd!!", you are an idiot.

Ok, so you've changed your mind then; the HEAD-redirect-to-GET isn't
anything unique.

Which leaves you with making people aware of the problems with
implicit-allow rules.  Which is old news.  Which is where we started
