{"id":"CVE-2026-101907","summary":"Axios: maxRedirects: 0 is not enforced by the fetch adapter, allowing redirect-based SSRF","details":"Axios is a promise-based HTTP client for the browser and Node.js. From 1.17.0 until 1.20.0, the fetch adapter bypasses the maxRedirects: 0 redirect policy. An Axios request uses the fetch adapter with maxRedirects set to zero and receives a redirect response. The underlying fetch implementation follows the redirect instead of returning the redirect response unchanged. The redirected request can access internal responses or reach state-changing internal endpoints despite redirects being disabled. This issue is fixed in version 1.20.0.","aliases":["GHSA-r4gj-5m52-g5wh"],"modified":"2026-09-30T03:47:03.441455167Z","published":"2026-09-28T17:36:03.648Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-441","CWE-601"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101907.json"},"references":[{"type":"WEB","url":"https://github.com/axios/axios/releases/tag/v1.20.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/101xxx/CVE-2026-101907.json"},{"type":"ADVISORY","url":"https://github.com/axios/axios/security/advisories/GHSA-r4gj-5m52-g5wh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-101907"},{"type":"FIX","url":"https://github.com/axios/axios/commit/d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"type":"FIX","url":"https://github.com/axios/axios/pull/11141"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/axios/axios","events":[{"introduced":"4306df21e84332fc576e98c2de549347c06bfb76"},{"fixed":"d19040bda7a8be2f82c3c6e1a5bc03917daee39a"},{"fixed":"84a9f3b9a4f3244b8c8e818f557d64c7b964fb25"}],"database_specific":{"extracted_events":[{"introduced":"1.17.0"},{"fixed":"1.20.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.19.0","v1.18.1","v1.18.0","v1.17.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-101907.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N"}]}
