Summary

find-my-way is a framework-independent HTTP router that internally uses a Radix Tree and supports route parameters and wildcards. Versions prior to 9.7.0 are vulnerable to remotely triggerable DoS in find-my-way when it is used with Node's HTTP/2 server. The lookup() function 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. This issue has been fixed in version 9.0.7.

Patch / fix

  • npm find-my-way 9.7.0
  • find-my-way_project find-my-way 9.7.0
