CVE-2026-47219Network attack vector

Unauthenticated HTTP/2 crash via inherited method lookup

Published Jul 28, 2026 · Updated Jul 28, 2026

Denial of service in delvedor FindMyWay before 9.7.0 allows remote attackers to crash Node.js HTTP/2 servers using a crafted method. lookup() passes req.method to find(), which indexes a normal-object method tree and treats inherited properties such as constructor as router nodes. Exploitation requires an application using Node.js HTTP/2 with unvalidated method values; the uncaught exception interrupts that server process.
