{"id":"CVE-2026-101898","summary":"Axios: HTTP/2 adapter bypasses configured DNS lookup and proxy controls","details":"Axios is a promise-based HTTP client for the browser and Node.js. From 1.13.0 until 1.20.0, Axios HTTP/2 request setup does not consistently apply proxy settings and caller-supplied DNS lookup policy. An HTTPS request uses httpVersion: 2 with explicit config.proxy or environment-derived proxy settings, or relies on caller-supplied config.lookup DNS policy. The HTTP/2 path can connect without the configured proxy behavior or without applying the caller-supplied config.lookup policy before http2.connect(). Requests can bypass the intended proxy route or the caller-supplied DNS resolution policy. This issue is fixed in version 1.20.0.","aliases":["GHSA-3pq3-5fj3-cg6v"],"modified":"2026-09-30T03:47:02.917048350Z","published":"2026-09-28T17:10:16.044Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101898.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/axios/axios/releases/tag/v1.20.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101898.json"},{"type":"ADVISORY","url":"https://github.com/axios/axios/security/advisories/GHSA-3pq3-5fj3-cg6v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-101898"},{"type":"FIX","url":"https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"type":"FIX","url":"https://github.com/axios/axios/pull/11141"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/axios/axios","events":[{"introduced":"9ead04d8abbcd53718dbc31b1250ea74300921c8"},{"fixed":"d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"fixed":"84a9f3b9a4f3244b8c8e818f557d64c7b964fb25"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"1.13.0"},{"fixed":"1.20.0"}]}}],"versions":["v1.19.0","v1.18.1","v1.18.0","v1.17.0","v1.16.1","v1.16.0","v1.15.2","v1.15.1","v1.15.0","v1.14.0","v1.13.6","v1.13.5","v1.13.4","v1.13.3","v1.13.2","v1.13.1","v1.13.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-101898.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N"}]}
