CVE-2026-44486

A flaw was found in Axios, a promise-based HTTP client, specifically in its Node.js HTTP adapter. When Axios is configured to use an authenticated proxy and follows a redirect, it may inadvertently send the Proxy-Authorization header, containing proxy credentials, to the redirect target. This can lead to the disclosure of sensitive proxy credentials to an unintended remote server.

This is an Important information disclosure flaw in the Axios Node.js HTTP adapter. Red Hat products utilizing Axios in a Node.js environment with an authenticated proxy and automatic redirects enabled are susceptible. The vulnerability arises when a request, initially sent through an authenticated proxy, is redirected to a target that no longer uses the proxy, potentially leaking Proxy-Authorization headers containing sensitive credentials to an untrusted remote server. This risk is heightened in deployments where applications interact with untrusted HTTP origins.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
