N8n Monitor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward n8n Docker monitoring helper with no hidden persistence, data export, or destructive behavior found.

Install only where the agent is allowed to inspect Docker and n8n logs, since logs may contain workflow details or secrets. The artifact itself does not show destructive actions, remote exfiltration, or persistence.

A.I.G

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
