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."}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')","cweId":"CWE-1321","type":"CWE"}]}],"affected":[{"vendor":"axios","product":"axios","defaultStatus":"unaffected","packageURL":"pkg:npm/axios","versions":[{"version":"1.0.0","status":"affected","versionType":"semver","lessThan":"1.18.0"},{"version":"1.18.0","status":"unaffected","versionType":"semver"}]},{"vendor":"axios","product":"axios","defaultStatus":"unaffected","packageURL":"pkg:npm/axios","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"0.33.0"},{"version":"0.33.0","status":"unaffected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:axios:axios:*:*:*:*:*:node.js:*:*","versionStartIncluding":"1.0.0","versionEndExcluding":"1.18.0"},{"vulnerable":true,"criteria":"cpe:2.3:a:axios:axios:*:*:*:*:*:node.js:*:*","versionEndExcluding":"0.33.0"}]}]}],"metrics":[{"format":"CVSS","cvssV4_0":{"version":"4.0","vectorString":"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","attackVector":"NETWORK","attackComplexity":"HIGH","attackRequirements":"PRESENT","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"NONE","vulnIntegrityImpact":"LOW","vulnAvailabilityImpact":"NONE","subConfidentialityImpact":"NONE","subIntegrityImpact":"NONE","subAvailabilityImpact":"NONE","baseScore":6.3,"baseSeverity":"MEDIUM"}}],"references":[{"url":"https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx","tags":["vendor-advisory"],"name":"GitHub Security Advisory (GHSA-mmx7-hfxf-jppx)"},{"name":"VulnCheck Advisory: axios before 1.18.0 Prototype Pollution via bodyless methods","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/axios-before-prototype-pollution-via-bodyless-methods"}],"credits":[{"lang":"en","value":"bilerden","type":"reporter"}],"x_generator":{"engine":"vulncheck-endgame"}},"adp":[{"references":[{"url":"https://github.com/axios/axios/security/advisories/GHSA-mmx7-hfxf-jppx","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-03T15:17:08.473731Z","id":"CVE-2026-67316","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-03T15:17:16.313Z"}}]}}
