{"id":"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.","aliases":["GHSA-c96f-x56v-gq3h"],"modified":"2026-08-01T03:33:07.744859605Z","published":"2026-07-28T22:14:31.279Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-20","CWE-248"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47219.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/delvedor/find-my-way","events":[{"introduced":"0"},{"fixed":"827248e64fe17e44cbd9690e4eb0121e51256385"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"9.7.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v9.6.0","v9.5.0","v9.4.0","v9.3.0","v9.1.0","v9.0.1","v8.2.0","v9.0.0","v8.1.0","v8.0.0","v7.7.0","v7.6.2","v7.6.1","v7.6.0","v7.5.0","v7.4.0","v7.3.1","v7.3.0","v7.2.1","v7.2.0","v7.1.0","v7.0.1","v7.0.0","v6.4.0","v6.3.0","v6.2.0","v6.1.0","v6.0.0","v5.6.0","v5.5.1","v5.5.0","v5.4.1","5.4.0","v5.3.0","v5.2.0","v5.1.1","v4.4.0","v5.1.0","v5.0.0","v4.3.3","v4.3.2","v4.3.1","v4.3.0","v4.2.0","v4.1.0","v4.0.0","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v2.2.2","v3.0.0","v2.2.1","v2.2.0","v2.1.2","v2.1.1","v2.1.0","v2.0.1","v2.0.0","v1.18.1","v1.18.0","v1.17.1","v1.17.0","v1.16.0","v1.15.4","v1.15.3","v1.15.2","v1.15.1","v1.15.0","v1.14.1","v1.14.0","v1.13.0","v1.12.0","v1.10.4","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.1","v1.9.0","v1.8.2","v1.8.1","v1.8.0","v1.7.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.0","v1.4.1","v1.4.0","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.1","v1.0.0","v0.2.4","v0.2.3","v0.2.2","v0.2.1","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47219.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
