Axios Critical Vulnerability Enables Full Cloud Compromise via Prototype Pollution Gadget

Summary

Axios patched a critical CVSS 10.0 vulnerability (CVE-2026-40175) that allows attackers to use prototype pollution gadgets to smuggle HTTP requests and bypass AWS IMDSv2 security. This flaw enables full cloud account compromise by exfiltrating IAM credentials without requiring direct user input.

Take Action:

If you use Axios in your applications, start planning an update to version 1.15.0 or later. The cat is out of the bag, and attackers can steal your cloud credentials without any direct user input. Audit your dependency tree for prototype pollution vulnerabilities in libraries like qs, minimist, and ini, since those are what give attackers the entry point for this exploit.
