NewCVE-2025-62718 (opens in a new tab)How to fix?
Upgrade axios to version 0.31.0, 1.15.0 or higher.
Overview
axios is a promise-based HTTP client for the browser and Node.js.
Affected versions of this package are vulnerable to Unintended Proxy or Intermediary ('Confused Deputy') via improper hostname normalization in the NO_PROXY environment variable. An attacker controlling request URLs can access internal or loopback services by crafting requests (with a trailing dot or [::1]) that bypass proxy restrictions, causing sensitive requests to be routed through an unintended proxy.
Note:
This is only exploitable if the application relies on NO_PROXY=localhost,127.0.0.1,::1 for protecting loopback/internal access.
