Axios is the central vector in two distinct high-severity exposure clusters. The first is a supply chain compromise (CVE-2026-33634, CVSS 9.5, priority 0.89) in which UNC1069 trojanized the Axios npm package to harvest credentials from downstream build pipelines including OpenAI, the European Commission, and Mercor; hundreds of thousands of secrets may have been exfiltrated. The second is a separate vulnerability (CVE-2026-40175, CVSS 9.1) combining HTTP header injection and SSRF that enables cloud metadata credential theft via IMDSv1 endpoints. Organizations should immediately audit all Axios versions in package-lock.json and dependency trees for the March 2026 compromise window, upgrade to a verified clean release, rotate all secrets accessible to affected build environments, and enforce IMDSv2 on AWS EC2 instances as a defense-in-depth control against the SSRF vector.
