CVE-2026-101907

Axios: maxRedirects: 0 is not enforced by the fetch adapter, allowing redirect-based SSRF

Published Sep 28, 2026 CVSS 4.0 · 7 High EPSS < 1% KEV · Not listed
Description
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.
