Axios: Proxy-Authorization header leaks to redirect target when proxy is re-evaluated to direct connection PUBLISHED

Description (CNA)

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios’ Node.js HTTP adapter can leak proxy credentials to a redirect target in affected versions. When a request is sent through an authenticated proxy, Axios may add a Proxy-Authorization header. If Axios then follows a redirect and the redirected request is no longer sent through that proxy, the stale Proxy-Authorization header can remain on the redirected request and be sent to the redirect target. This affects Node.js's use of Axios with automatic redirects enabled and an authenticated proxy configuration. Browser adapters are not affected. This vulnerability is fixed in 0.32.0 and 1.16.0.

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.
