{"cve":"CVE-2026-47219","nvd":{"published":"2026-07-28T23:17:03.763","modified":"2026-10-23T23:10:00.157","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-20","CWE-248"],"references":["https://github.com/delvedor/find-my-way/security/advisories/GHSA-c96f-x56v-gq3h"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-47219","score":0.0046,"percentile":0.39598,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-c96f-x56v-gq3h","url":"https://osv.dev/vulnerability/GHSA-c96f-x56v-gq3h","summary":"find-my-way: DDoS with HTTP2","modified":"2026-07-23T19:56:40.779403Z","packages":[{"ecosystem":"npm","name":"find-my-way","purl":"pkg:npm/find-my-way","ranges":["<9.7.0"],"fixed":["9.7.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
