tm_ai-2.0.6/PKG-INFO:84
# 🎧 macOS / Linux / WSL
curl -fsSL https://jaimeena.com/cvc/install.sh | bash
Why was this flagged?
A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.

version="0.1.0",
cmdclass={"lint": LintCommand},
)Why was this flagged?
This package overrides Python's setup.py cmdclass, which allows arbitrary code to execute during pip install. This is the primary attack vector for malicious PyPI packages — attackers use it to steal credentials, install backdoors, or download additional payloads before the developer ever runs the code. Rated CRITICAL because it executes automatically with no user interaction required.

# ---------------------------------------------------------------------------
# setup (guided first-time configuration)
# ---------------------------------------------------------------------------Why was this flagged?
This setup.py calls subprocess, os.system, exec, or eval during package installation. Legitimate packages rarely need to execute arbitrary commands at install time. This pattern is commonly used by malicious packages to download and run payloads, exfiltrate environment variables, or establish persistence. Rated CRITICAL because it runs with the installer's full permissions.
