install-makefile-curl
HIGHMakefile/script pipes remote content to shell
package/README.md:14
# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/orchestra-mcp/framework/master/scripts/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-makefile-curl
HIGHMakefile/script pipes remote content to shell
package/README.md:17
# Windows (Git Bash)
curl -fsSL --ssl-revoke-best-effort https://raw.githubusercontent.com/orchestra-mcp/framework/master/scripts/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-npm-postinstall
CRITICALnpm lifecycle script — runs automatically on install
package/package.json:24
"scripts": {
"postinstall": "node scripts/npm-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.
