N8n Dispatch

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says, but it forwards home-automation prompts and action requests to an n8n service using weak scoping and unsafe transport guidance.

Review before installing. Use this only with an n8n workflow you control, prefer HTTPS or local-only loopback, add authentication and least-privilege checks in n8n, and avoid sending secrets or sensitive household details until the command validates requestType and builds JSON with a real serializer.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

Missing User Warnings

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The skill explicitly forwards the raw user prompt to an external MCP/n8n service, but provides no warning that user-entered content leaves the local environment. This creates a real privacy and data-handling risk because users may unknowingly send secrets, personal data, or operationally sensitive requests to a remote service outside the immediate agent boundary.
