CVE-2026-101907 · Severity: high · CVSS 4 · Published 2026-09-28

Axios, a popular HTTP client library for JavaScript, contains a flaw in versions 1.17.0 through 1.20.0 where the fetch adapter ignores the maxRedirects: 0 setting and follows HTTP redirects anyway. An attacker could exploit this to access internal endpoints or retrieve sensitive responses that an application intended to block, potentially leading to unauthorized data access or unwanted state changes.

## How to fix

- axios (npm): upgrade to 1.20.0 or later

  ```sh
  npm install axios@1.20.0
  ```


## Technical details

The vulnerability exists in the fetch adapter's handling of the maxRedirects configuration option. When maxRedirects is set to 0 (disabling redirects), the underlying fetch implementation continues to follow redirects, exposing internal responses or allowing access to internal state-changing endpoints. The issue is resolved in version 1.20.0 by properly honoring the maxRedirects: 0 setting and preventing automatic redirect following in the fetch adapter.
