CVE-2026-67315
axios 0.31.0 before 0.33.0 and 1.15.0 before 1.18.0 NO_PROXY Bypass via 0.0.0.0
MEDIUM 6.9EPSS 0.5%
axios versions 0.31.0 before 0.33.0 and 1.15.0 before 1.18.0 fail to recognize 0.0.0.0 as a loopback address in shouldBypassProxy.js, allowing requests to 0.0.0.0 to bypass NO_PROXY rules. Attackers can supply 0.0.0.0 URLs to route requests through configured proxies, potentially exposing local services when the proxy can reach the destination.
