{"id":"GHSA-f2r5-pqh9-r8f8","summary":"Duplicate Advisory: Axios: Prototype pollution gadgets can alter axios request construction","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-mmx7-hfxf-jppx. This link is maintained to preserve external references.\n\n## Original Description\naxios 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is fixed in axios 1.18.0 and 0.33.0.","modified":"2026-09-10T03:51:13.925198037Z","published":"2026-08-01T15:30:27Z","withdrawn":"2026-08-31T19:51:19Z","database_specific":{"github_reviewed_at":"2026-08-31T19:51:19Z","nvd_published_at":"2026-08-01T13:17:01Z","cwe_ids":["CWE-1321"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","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":"WEB","url":"https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods"}],"affected":[{"package":{"name":"axios","ecosystem":"npm","purl":"pkg:npm/axios"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"last_known_affected_version_range":"\u003c 0.33.0","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-f2r5-pqh9-r8f8/GHSA-f2r5-pqh9-r8f8.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
