axios : Unintended Proxy or Intermediary (Confused Deputy) Vulnerability - CVE-2026-101907

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.
