{"id":"CVE-2026-47219","state":"PUBLISHED","title":"find-my-way is Vulnerable to DDoS with HTTP2","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.","publishedAt":"2026-07-28T22:14:31.279Z","updatedAt":"2026-07-29T15:24:01.203Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["delvedor find-my-way"],"affected":[{"vendor":"delvedor","product":"find-my-way","versions":[{"version":"< 9.7.0","status":"affected"}]}],"references":["https://github.com/delvedor/find-my-way/security/advisories/GHSA-c96f-x56v-gq3h"],"weaknesses":["CWE-20","CWE-248"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/47xxx/CVE-2026-47219.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-47219","state":"PUBLISHED","datePublished":"2026-07-28T22:14:31.279Z","dateUpdated":"2026-07-29T15:24:01.203Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-18T22:25:21.258Z"},"containers":{"cna":{"title":"find-my-way is Vulnerable to DDoS with HTTP2","descriptions":[{"lang":"en","value":"find-my-way is a framework-independent HTTP router that internally uses a Radix Tree and supports route parameters and wildcards.
