NewCVE-2026-67315 (opens in a new tab)How to fix?
Upgrade org.webjars.npm:axios to version 1.18.0 or higher.
Overview
org.webjars.npm:axios is a promise-based HTTP client for the browser and Node.js.
Affected versions of this package are vulnerable to Permissive List of Allowed Inputs in the isLoopback() and isIPv4Loopback() functions of lib/helpers/shouldBypassProxy.js, which require the first IPv4 octet to be 127 and therefore do not recognize 0.0.0.0 as a loopback address. An attacker who controls the request URL or a redirect target can bypass the NO_PROXY policy for local addresses and route requests to http://0.0.0.0:<port>/ through the configured proxy, reaching internal services, cloud IMDS endpoints, or microservice APIs. Exploitation requires the Node HTTP adapter with HTTP_PROXY or HTTPS_PROXY set and NO_PROXY listing local addresses, attacker control over the URL or redirect target, and a proxy able to reach the local destinations.
Workaround
This vulnerability can be avoided by explicitly adding 0.0.0.0 to the NO_PROXY list, so requests to it are excluded from the proxy as the loopback check intended.
