From 0.27.2 until 0.34.0 and 1.20.0, Axios default-instance requests that omit an explicit method can read an inherited method value from Object.prototype. If another vulnerability in the same process pollutes Object.prototype.method, calls such as axios.request({ url }) and axios({ url }) can send a state-changing HTTP method instead of the expected default GET. Axios does not create the prototype pollution source. This is a read-side gadget in axios request dispatch. This issue is fixed in version 0.34.0 and 1.20.0.","state":0,"publishedAt":"2026-09-28T17:22:49.113+00:00","modifiedAt":"2026-09-28T19:30:19.51+00:00","affected":[{"ecosystem":"Vendor product","name":"axios","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"axios\",\n                    \"product\": \"axios\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.0.0, < 1.20.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 0.27.2, < 0.34.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:H/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/axios/axios/security/advisories/GHSA-9fr6-4gfg-395g","https://github.com/axios/axios/pull/11141","https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a","https://github.com/axios/axios/releases/tag/v0.34.0","https://github.com/axios/axios/releases/tag/v1.20.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-101902","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-101902","identifiers":["CVE-2026-101902"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
