A remotely triggerable Denial of Service (DoS) vulnerability exists in the 'find-my-way' router when used with Node.js HTTP/2 servers. Malicious HTTP/2 method values, such as 'constructor' or '__proto__', can be passed to the 'lookup()' function, which then indexes these values against internal data structures. This leads to a crash when the code attempts to access properties of these unexpected values, such as 'currentNode.prefix.length', causing the server to become unavailable. Users are advised to upgrade to version 9.7.0 or validate HTTP methods before processing.
