install-makefile-curl
HIGHMakefile/script pipes remote content to shell
package/dist/executors/cursor-agent.executor.js:34
if (!cursorAgentPath) {
return { type: 'NOT_FOUND', error: 'Cursor Agent CLI not installed. Run: curl https://cursor.com/install -fsS | 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.
install-pip-setup-exec
CRITICALsetup.py executes code at install time
package/dist/web/assets/ProjectKanbanPage-x3ZQWJIh.js:6

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.
install-npm-postinstall
CRITICALnpm lifecycle script — runs automatically on install
package/package.json:21
"scripts": {
"postinstall": "node scripts/postinstall.js"
},Why 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.
