• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-08-01 · updated 2026-09-01
• Weakness: CWE-183

Description

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.

Affected products

• axios: from 0.31.0 before 0.33.0; from 1.15.0 before 1.18.0 — fixed in 0.33.0, 1.18.0

How to fix

Upgrade to a fixed version: axios 0.33.0, 1.18.0. Check the vendor advisory for mitigations.
