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.","dates":{"published":"2026-08-01T15:30:27.000Z","modified":"2026-09-10T03:51:13.925Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.3,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"OSV · Npm","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/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","computed":true,"selection":"version-preference"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"OSV · Npm","score":6.3,"severity":"medium","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/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","exploitability":null,"impact":null,"computed":true}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"Npm","product":"axios","name":"axios","label":"axios","ecosystem":"Npm","cpePart":null,"purl":"pkg:npm/axios","purlType":"npm","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx","label":"github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx","hostname":"github.com","tags":["WEB"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67316","label":"nvd.nist.gov/vuln/detail/CVE-2026-67316","hostname":"nvd.nist.gov","tags":["Advisory"]},{"url":"https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods","label":"www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods","hostname":"www.vulncheck.com","tags":["WEB"]}],"lineage":{"upstream":[],"downstream":["CVE-2026-67316"],"duplicates":[],"related":["CGA-693J-HH55-PQ7V"]},"timeline":[{"kind":"published","date":"2026-08-01T15:30:27.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-09-10T03:51:13.925Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":25,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-22T12:33:44.939Z","stale":false,"partial":false}}
