CVE-2026-47219
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
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.
