{"id":"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.","aliases":["GHSA-mmx7-hfxf-jppx"],"modified":"2026-08-03T03:30:27.274027875Z","published":"2026-08-01T12:22:18.114Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67316.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-1321"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/axios/axios","events":[{"introduced":"484aa4fe6addccbd32206a31eb3d2d000843066e"},{"fixed":"2d06f96e8602c2db13b65a26340ee4a1bbc0b61f"},{"introduced":"0"},{"fixed":"d998cc9a1aa5cc45fbdfbdded6e9ecf8beb61aed"}],"database_specific":{"extracted_events":[{"introduced":"1.0.0"},{"fixed":"1.18.0"},{"introduced":"0"},{"fixed":"0.33.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.17.0","v1.16.1","v0.32.0","v0.31.1","v1.16.0","v1.15.2","v1.15.1","v0.31.0","v1.15.0","v1.14.0","v1.13.6","v0.30.3","v0.30.2","v1.13.5","v1.13.4","v1.13.3","v1.13.2","v1.13.1","v1.13.0","v0.30.1","v1.12.2","v1.12.1","v1.12.0","v0.30.0","v1.11.0","v1.10.0","v1.9.0","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v0.29.0","v1.7.9","v1.7.8","v1.7.7","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v0.28.1","v1.7.1","v1.7.0","v1.7.0-beta.2","v1.7.0-beta.1","v1.7.0-beta.0","v1.6.8","v1.6.7","v0.28.0","v1.6.6","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.4.0","v1.3.6","v1.3.5","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.6","v1.2.5","v1.2.4","v1.2.3","v1.2.2","1.2.2","v1.2.1","v1.2.0","1.2.0-alpha.1","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.0","v0.27.2","v0.27.1","v0.27.0","v0.26.0","v0.26.1","v0.25.0","v0.24.0","v0.23.0","0.21.3","v0.21.2","v0.21.0","v0.20.0","v0.20.0-0","v0.19.2","0.19.1","v0.19.1","v0.19.0","v0.18.0","v0.19.0-beta.1","v0.17.1","v0.17.0","v0.16.2","v0.16.1","v0.16.0","v0.15.3","v0.15.2","v0.15.1","v0.15.0","v0.14.0","v0.13.1","v0.13.0","v0.12.0","v0.11.1","v0.11.0","v0.10.0","v0.9.1","v0.9.0","v0.8.1","v0.8.0","v0.7.0","v0.6.0","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.1","v0.3.0","v0.2.2","v0.2.1","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67316.json"}}],"schema_version":"1.7.5","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"}]}
