CVE-2025-62718

A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not correctly handle hostname normalization when evaluating NO_PROXY rules. An attacker can exploit this by crafting requests to loopback addresses (e.g., localhost. or [::1]) which bypass the NO_PROXY configuration and are routed through the configured proxy. This can lead to Server-Side Request Forgery (SSRF) vulnerabilities, enabling attackers to access sensitive internal or loopback services that should otherwise be protected.

This flaw has limited impact due to combination of non-default conditions to exploit: the attacker must be able to control or influence URLs passed to axios in a server-side context, the application must have both HTTP_PROXY and NO_PROXY configured, and the proxy itself must be positioned to act on the misdirected traffic or have been compromised by the attacker to intercept the rerouted traffic.
