AI Summary

CISA issued an alert on April 20, 2026 about a supply‑chain compromise affecting the Axios npm package. On March 31, 2026, the Axios versions 1.14.1 and 0.30.4 were found to include a malicious dependency, plain‑crypto‑js 4.2.1, which downloads multi‑stage payloads from threat‑actor infrastructure, including a remote‑access trojan. CISA recommends that organizations monitor code repositories, CI/CD pipelines, and developer machines that ran npm install or update with the compromised Axios version. They also advise searching artifact repositories for cached affected dependencies, pinning npm package versions to known safe releases, and reverting environments to a safe state if a compromise is detected.
