A high-severity vulnerability (CVE-2026-42043) in the axios HTTP client library allowed attackers to bypass NO_PROXY environment variable restrictions using specially crafted URLs. This could route sensitive internal traffic through attacker-controlled proxy servers. The fix upgrades axios from 1.13.6 to 1.18.0, which includes a rewritten proxy resolution mechanism using `proxy-from-env` v2.1.0 and the `https-proxy-agent` package.
A high-severity vulnerability (CVE-2026-42043) in axios versions prior to 1.15.1 allowed attackers to bypass NO_PROXY environment variable restrictions using specially crafted URLs. This meant HTTP requests intended to stay internal could be routed through an attacker-controlled proxy, potentially exposing sensitive data. The fix upgrades axios to version 1.15.1, which correctly validates URLs against NO_PROXY rules.
