Security audit

Commander.js is the most popular command-line interface (CLI) framework for Node.js.

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward Commander.js reference skill with example CLI code and no hidden agent-control or persistence behavior.

This skill appears safe to install as documentation for Commander.js. When using its examples, review normal Node.js dependency changes such as adding `commander` to a project.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
