find-my-way: DDoS with HTTP2
Remotely triggerable DoS in find-my-way when it is used with Node's HTTP/2 server. The short version is that lookup() passes req.method into find(), and find() indexes this.trees[method]. Since this.trees is a normal object, HTTP/2 method values like constructor, toString, or proto can resolve inherited object properties instead of returning undefined. The code then treats that value like a router node and crashes when it reaches currentNode.prefix.length.
