{"id":"CVE-2026-67316","aliases":["GHSA-mmx7-hfxf-jppx"],"url":"https://o3.security/vulnerability/CVE-2026-67316","summary":"axios before 1.18.0 Prototype Pollution via bodyless methods","details":"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.","published":"2026-08-01T12:22:18.114Z","modified":"2026-09-02T03:31:00.761931509Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"axios","fixedVersion":"1.18.0"},{"ecosystem":"npm","name":"axios","fixedVersion":"0.33.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67316.json"},{"type":"ADVISORY","url":"https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67316"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-02T03:31:00.761931509Z"}}
