What is CVE-2026-44486?

Axios, a popular promise-based HTTP client, has a vulnerability that allows proxy credentials to be inadvertently leaked during redirect responses. When a request is made through an authenticated proxy, the Proxy-Authorization header may be included. If the request then follows a redirect to a different target that is outside of the proxy's scope, this outdated header may still be used, leading to exposure of sensitive authentication information. This issue impacts users who utilize Node.js with Axios configured for automatic redirections and authenticated proxies. It is essential for developers to upgrade to versions 0.32.0 or 1.16.0 to mitigate this risk.

Affected Version(s)

axios >= 1.0.0, < 1.16.0 < 1.0.0, 1.16.0

axios < 0.32.0 < 0.32.0
