CVE-2026-44487

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.

This is an Important information disclosure flaw in Axios affecting Node.js environments. When an application uses Axios with an authenticated HTTP proxy and follows redirects from an HTTP to a non-proxied HTTPS destination, the Proxy-Authorization header may be inadvertently sent to the final origin server. This could lead to the exposure of sensitive proxy credentials to an unintended third party.
