What happened
Feed of Snyk blog advisories (late Apr 2026) describing multiple active supply-chain compromises and a high‑severity template injection: 1) Malicious PyPI releases (lightning, elementary-data v0.23.3) and compromised npm packages (Mini Shai‑Hulud) delivering Bun‑based credential stealers/backdoors that run on import and exfiltrate cloud provider keys, dbt profiles, SSH secrets and other CI/CD credentials (one elementary-data release tied to a GitHub Actions script injection). 2) A high‑impact Thymeleaf template injection (CVE‑2026‑40478, CVSS 9.1) requiring patching to 3.1.4+ and code audits.S
