axios: Axios: Server-Side Request Forgery and proxy bypass due to improper hostname normalization

A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not correctly handle hostname normalization when evaluating NOPROXY rules. An attacker can exploit this by crafting requests to loopback addresses e.g., localhost. or ::1 which bypass the NOPROXY...

Security Bulletin: Axios NO_PROXY Bypass via Improper Hostname Normalization Leads to SSRF

Summary 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 NOPROXY rules. Requests to loopback addresses like localhost. with a trailing dot or ::1 IPv6 literal skip NOPROXY matching an...

CVE-2026-42038 Axios: no_proxy bypass via IP alias allows SSRF

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, he fix for noproxy hostname normalization bypass is incomplete. When noproxy=localhost is set, requests to 127.0.0.1 and ::1 still route through the proxy instead of bypassing it. The shouldBypassProxy...

CVE-2026-42038

Axios no_proxy bypass via IP alias allows SSRF in older releases. Affected: Axios (browser/Node.js). Fault: shouldBypassProxy() uses pure string matching and does not resolve IP aliases or loopback equivalents, so requests to 127.0.0.1 or [::1] can be proxied when no_proxy=localhost. Impact: pote...
