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"}}}}
