install-makefile-curl
HIGHMakefile/script pipes remote content to shell
repo/README.md:142
- Ensure you have uv installed: `curl -LsSf https://astral.sh/uv/install.sh | sh`
- Check uv version: `uv --version` (should be 0.4.0 or higher)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.
install-makefile-curl
HIGHMakefile/script pipes remote content to shell
repo/README.md:346
# 2. Install UV package manager (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh
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.
install-pip-setup-exec
CRITICALsetup.py executes code at install time
repo/linkedin_mcp_server/bootstrap.py:183
_state.setup_completed_at = None
_state.setup_task = asyncio.create_task(_run_browser_setup(), name="browser-setup")
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.
