Two separate Bun-based credential-stealer campaigns surfaced: a malicious lightning PyPI release that runs on import and the “Mini Shai‑Hulud” Bun stealer that compromised several SAP-related npm packages; both exfiltrate credentials. A malicious release of the elementary-data PyPI CLI (v0.23.3) used a GitHub Actions script-injection to publish a backdoor that targets dbt profiles, cloud provider keys, and SSH secrets. Separately, Thymeleaf template injection (CVE-2026-40478, CVSS 9.1) is critical but exploit
