Prior to 0.32.0 and 1.16.0, axios exposes two read-side prototype-pollution gadgets. When Object.prototype is polluted by an upstream dependency in the same process (e.g. lodash _.merge / CVE-2018-16487), axios silently picks up the polluted values. (1) lib/utils.js line 406 builds merge()'s accumulator as result = {}, so result[targetKey] (line 414) walks Object.prototype and the polluted bucket's own keys are copied into the merged headers and ride out on the wire. (2) lib/core/mergeConfig.js line 26 builds the hasOwnProperty descriptor as a plain-object literal. Object.defineProperty reads descriptor.get/descriptor.set via the prototype chain, so a polluted Object.prototype.get or Object.prototype.set makes the call throw TypeError synchronously on every axios request. This vulnerability is fixed in 0.32.0 and 1.16.0."}], "lastModified": "2026-06-17T10:50:43.067", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:axios:axios:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "CC9D9AB4-047A-4638-AF10-7D08587A01C8", "versionEndExcluding": "0.32.0"}, {"criteria": "cpe:2.3:a:axios:axios:*:*:*:*:*:node.js:*:*", "vulnerable": true, "matchCriteriaId": "BE82EB7B-A379-416F-9737-4191F720B8C6", "versionEndExcluding": "1.16.0", "versionStartIncluding": "1.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
