{"cve":"CVE-2026-67316","nvd":{"published":"2026-08-01T13:17:01.673","modified":"2026-09-01T15:40:01.880","status":"Analyzed","description":"axios is vulnerable to read-side prototype-pollution gadgets that can alter request construction when Object.prototype has already been polluted by a separate vulnerability or dependency. In the bodyless method aliases (axios.get(), axios.delete(), axios.head(), axios.options()), inherited data is read via (config || {}).data before config normalization, causing an attacker-controlled body to be sent on requests that did not set one. Additional low-level paths, only reachable when calling exported adapters/helpers (e.g. lib/adapters/http.js, unsafe/helpers/resolveConfig.js) directly with plain configs and no own proxy or paramsSerializer, can inherit polluted proxy values (routing requests through an attacker-controlled proxy) or paramsSerializer values (attacker-controlled URL serialization). These low-level gadgets do not reproduce through normal high-level axios calls on 1.15.2+. The issue is fixed in axios 1.18.0 and 0.33.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","score":7.4},"cwes":["CWE-1321"],"references":["https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx","https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods","https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx"],"products":["axios:axios"],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-67316","score":0.00424,"percentile":0.36738,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-mmx7-hfxf-jppx","url":"https://osv.dev/vulnerability/GHSA-mmx7-hfxf-jppx","summary":"Axios: Prototype pollution gadgets can alter axios request construction","modified":"2026-09-10T03:50:52.753640421Z","packages":[{"ecosystem":"npm","name":"axios","purl":"pkg:npm/axios","ranges":[">=1.0.0 <1.18.0"],"fixed":["1.18.0"]},{"ecosystem":"npm","name":"axios","purl":"pkg:npm/axios","ranges":["<0.33.0"],"fixed":["0.33.0"]}]}],"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).
