{"id":"CVE-2026-47219","aliases":["GHSA-c96f-x56v-gq3h"],"url":"https://o3.security/vulnerability/CVE-2026-47219","summary":"find-my-way is Vulnerable to DDoS with HTTP2","details":"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.","published":"2026-07-28T22:14:31.279Z","modified":"2026-08-12T03:51:19.141558100Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00263,"percentile":0.17965,"asOf":"2026-09-06"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"find-my-way","fixedVersion":"9.7.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47219.json"},{"type":"ADVISORY","url":"https://github.com/delvedor/find-my-way/security/advisories/GHSA-c96f-x56v-gq3h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47219"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:19.141558100Z"}}
