CVE-2025-62718
Description
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.
Statement
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.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
