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.","state":0,"publishedAt":"2026-07-28T22:14:31.279+00:00","modifiedAt":"2026-07-29T15:24:01.203+00:00","affected":[{"ecosystem":"Vendor product","name":"find-my-way","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"delvedor\",\n                    \"product\": \"find-my-way\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 9.7.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/delvedor/find-my-way/security/advisories/GHSA-c96f-x56v-gq3h"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-47219","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-47219","identifiers":["CVE-2026-47219"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
