From 1.12.0 until 1.20.0, ResolveConfig reads inherited Symbol.toStringTag, append, and getHeaders properties while resolving FormData headers. A separate same-process prototype-pollution flaw supplies an array or non-plain class instance whose inherited properties make it appear FormData-like; plain objects are blocked. The inherited getHeaders function can return attacker-controlled headers that resolveConfig merges into a fetch adapter request. Attacker-controlled headers can alter authorization, cache, metadata-service, or application-specific request behavior. This issue is fixed in version 1.20.0.","state":0,"publishedAt":"2026-09-28T18:17:18.05+00:00","modifiedAt":"2026-09-30T19:38:27.293+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:H/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","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a","https://github.com/axios/axios/pull/11141","https://github.com/axios/axios/releases/tag/v1.20.0","https://github.com/axios/axios/security/advisories/GHSA-4hqw-qxg8-jxx2"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-101900","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-74","CWE-693","CWE-1321"],"productCriteria":[],"sourceDates":{"published":"2026-09-28T18:17:18.050","lastModified":"2026-09-30T19:38:27.293"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
