MAL-2026-5766

Summary: Malicious code in easyllmai (PyPI)

Details: Source: amazon-inspector (4589bbb71e0bb3589a162bf2102bba5e8bf7124d3988235647d1e3c1d01821d0) During `pip install`, setup.py performs an unauthenticated HTTP fetch of https://pastebin.com/raw/yBcUM1QB, takes the first line of the response, and passes it directly to `os.system(f'cmd /c "{cmd_pastebin}"')`. The remote content is hosted on an anonymous, mutable, attacker-controlled paste with no pinning, no hash check, and no signature verification. Whoever controls the paste obtains arbitrary command execution on every installer's machine at install time. This is a canonical install-time dropper pattern: lifecycle-time outbound fetch from an unverified source piped straight into the OS shell.
