An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47219 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- find-my-way (npm): affected all versions; fixed in 9.7.0\n- find-my-way (npm): affected all versions; fixed in 9.7.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-47219/ (Markdown: https://insights.sbomify.com/CVE-2026-47219/index.md)","id":"CVE-2026-47219","markdown":"https://insights.sbomify.com/CVE-2026-47219/index.md","name":"CVE-2026-47219","record":{"aliases":["CLSA-2026-1785291246","CLSA-2026-1792488967","CLSA-2026-1792489084","GHSA-c96f-x56v-gq3h","MINI-9p3p-m3qv-j7v3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Node.js HTTP router","requires_auth":"none","summary":"Remote attackers can crash Node.js HTTP/2 servers using the find-my-way router by sending requests with malicious HTTP methods.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-248","name":"Uncaught Exception"},{"id":"CWE-20","name":"Improper Input Validation"}],"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.
