{"id":"CVE-2026-67316","state":"PUBLISHED","title":"axios before 1.18.0 Prototype Pollution via bodyless methods","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.","publishedAt":"2026-08-01T12:22:18.114Z","updatedAt":"2026-08-03T15:17:16.313Z","severity":{"score":6.3,"label":"Medium","version":"4.0","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","source":"VulnCheck"},"assigner":"VulnCheck","products":["axios axios"],"affected":[{"vendor":"axios","product":"axios","packageURL":"pkg:npm/axios","defaultStatus":"unaffected","versions":[{"version":"1.0.0","status":"affected","lessThan":"1.18.0","versionType":"semver"},{"version":"1.18.0","status":"unaffected","versionType":"semver"}]},{"vendor":"axios","product":"axios","packageURL":"pkg:npm/axios","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"0.33.0","versionType":"semver"},{"version":"0.33.0","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx","https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods"],"weaknesses":["CWE-1321"],"ingestedAt":"2026-10-29T20:12:41.951Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/67xxx/CVE-2026-67316.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-67316","state":"PUBLISHED","datePublished":"2026-08-01T12:22:18.114Z","dateUpdated":"2026-08-03T15:17:16.313Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-07-29T13:06:35.179Z"},"containers":{"cna":{"title":"axios before 1.18.0 Prototype Pollution via bodyless methods","descriptions":[{"lang":"en","value":"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.
