{"cve":"CVE-2026-101901","nvd":{"published":"2026-09-28T18:17:18.233","modified":"2026-10-01T15:17:24.077","status":"Undergoing Analysis","description":"Axios is a promise-based HTTP client for the browser and Node.js. From 1.13.0 until 1.20.0, Http2Sessions does not install adequate error handling for a ClientHttp2Session during Axios HTTP/2 session initialization or reuse. A request uses httpVersion: 2 and the ClientHttp2Session emits an error during session initialization or reuse. The unhandled session error escapes normal Promise rejection handling. The uncaught error can terminate the Node.js process and cause denial of service. This issue is fixed in version 1.20.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":null,"cwes":["CWE-400"],"references":["https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a","https://github.com/axios/axios/pull/11141","https://github.com/axios/axios/releases/tag/v1.20.0","https://github.com/axios/axios/security/advisories/GHSA-542g-h47m-68v8","https://github.com/axios/axios/security/advisories/GHSA-542g-h47m-68v8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:48.555445741+00:00"},"epss":{"cve":"CVE-2026-101901","score":0.00536,"percentile":0.44909,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-542g-h47m-68v8","url":"https://osv.dev/vulnerability/GHSA-542g-h47m-68v8","summary":"Axios: Denial of Service via Unhandled 'error' Event in HTTP/2 ClientHttp2Session Initialization","modified":"2026-09-30T15:15:04.061469672Z","packages":[{"ecosystem":"npm","name":"axios","purl":"pkg:npm/axios","ranges":[">=1.13.0 <1.20.0"],"fixed":["1.20.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
