CVE-2026-44487 axios CVE debrief

Who should care

Defenders responsible for Node.js deployments using Axios should assess exposure and prioritize verification and remediation due to potential unauthorized access or elevation of privileges. They should verify Axios versions and configurations, implement compensating controls for affected deployments, and monitor for suspicious activity.

Why it matters

Defenders should care about CVE-2026-44487 because it affects Axios's Node.js HTTP adapter, potentially allowing proxy credentials to be forwarded to redirected origins. This vulnerability requires verification of Axios versions and configurations, and may lead to unauthorized access or elevation of privileges in affected deployments.

• Potential unauthorized access to proxy credentials
• Possible elevation of privileges in affected deployments
• Need for verification of Axios versions and configurations
• Potential for credential exposure in redirect flows

Technical summary

The Axios Node.js HTTP adapter may forward a Proxy-Authorization header to a redirected origin during specific proxy-to-direct redirect flows. This affects Node.js usage where an initial HTTP request is sent through an authenticated HTTP proxy, redirects are followed, and the redirected URL is no longer proxied. The vulnerability allows the final origin to receive the proxy credential intended only for the outbound proxy, potentially leading to unauthorized access or elevation of privileges in affected deployments.

Defensive priority

Defenders should prioritize verifying and upgrading to Axios versions 0.32.0 or 1.16.0, assessing exposure in Node.js usage, and implementing compensating controls for affected deployments.

Recommended defensive actions

• Verify and upgrade to Axios versions 0.32.0 or 1.16.0
• Assess exposure in Node.js usage
• Implement compensating controls for affected deployments
• Monitor for suspicious activity
• Review and update security configurations
