CVE-2025-62718 is a server-side request forgery and proxy-bypass vulnerability in Axios, the promise-based HTTP client for browsers and Node.js. In vulnerable versions prior to 1.15.0 on the 1.x branch and prior to 0.31.0 on the 0.x branch, Axios does not correctly normalize hostnames before evaluating NO_PROXY rules. As a result, loopback destinations represented in alternate but equivalent forms, including a hostname with a trailing dot and an IPv6 loopback literal, may fail NO_PROXY matching and be treated as proxy-eligible destinations. This breaks expected proxy exclusion behavior for localhost and internal targets and can allow attacker-controlled request destinations to traverse a configured proxy despite protections intended to prevent access to loopback or internal services.
