### Impact 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`. ### Patches Upgrade to v9.7.0. ### Workarounds Do not use find-my-way with HTTP/2 servers, or validate that the http method is valid beforehand.
