Description

A flaw was found in Axios, a software library used for making web requests. This vulnerability allows an attacker to bypass the `no_proxy` configuration, which is designed to prevent certain internal network requests from being sent through an external proxy. Specifically, when `no_proxy=localhost` is set, requests intended for local system addresses (such as 127.0.0.1 and [::1]) are still routed through the proxy. This could lead to unintended exposure of internal network traffic or sensitive information.
