Axios: Proxy-Authorization Credential Leak to Origin Server Across HTTP-to-HTTPS Redirect in Axios Node.js HTTP Adapter 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’s Node.js HTTP adapter may forward a Proxy-Authorization header to a redirected origin during specific proxy-to-direct redirect flows. This affects Node.js usage, where an initial HTTP request is sent through an authenticated HTTP proxy, redirects are followed, and the redirected URL is no longer proxied. Under affected redirect shapes, the final origin can receive the proxy credential that was intended only for the outbound proxy. This vulnerability is fixed in 0.32.0 and 1.16.0.

A flaw was found in Axios. During specific proxy-to-direct redirect flows in the Node.js HTTP adapter, a remote attacker could exploit this vulnerability. The Proxy-Authorization header, which contains proxy credentials and is intended only for the outbound proxy, may be forwarded to the final redirected origin. This can lead to the disclosure of sensitive proxy credentials to an unintended third party.
