AI description

Automated description summarized from trusted sources.

CVE-2025-62718 is a vulnerability affecting Axios, a promise-based HTTP client for browsers and Node.js, specifically in versions prior to 1.15.0. The issue stems from Axios's incorrect handling of hostname normalization when evaluating `NO_PROXY` rules. This flaw allows requests to loopback addresses, such as `localhost.` (with a trailing dot) or `[::1]` (an IPv6 literal), to bypass `NO_PROXY` configurations and be routed through a proxy. This normalization bypass can lead to proxy bypass and Server-Side Request Forgery (SSRF) vulnerabilities. Attackers could exploit this to force requests through a proxy, potentially gaining unauthorized access to sensitive loopback or internal services that are intended to be protected by `NO_PROXY` settings. The vulnerability is resolved in Axios version 1.15.0.

Description: Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.0 and 0.31.0, Axios does not correctly handle hostname normalization when checking NO_PROXY rules. Requests to loopback addresses like localhost. (with a trailing dot) or [::1] (IPv6 literal) skip NO_PROXY matching and go through the configured proxy. This goes against what developers expect and lets attackers force requests through a proxy, even if NO_PROXY is set up to protect loopback or internal services. This issue leads to the possibility of proxy bypass and SSRF vulnerabilities allowing attackers to reach sensitive loopback or internal services despite the configured protections. This vulnerability is fixed in 1.15.0 and 0.31.0.
