Security audit

Node Red Manager

Security checks for vulnerabilities and agentic risk

Overview

This Node-RED administration skill is mostly purpose-aligned, but it exposes broad mutation and Docker control without clear safety gates or scoping.

Install only if you intend to let the agent administer a specific Node-RED instance. Before allowing changes, verify NODE_RED_URL points to your own server, keep credentials scoped to that instance, require confirmation for deploy/delete/restore/node install or remove/Docker restart actions, and take a backup first.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The description states "移除风险代码,增强安全性和稳定性" at L019, suggesting the skill has had risky behavior removed. However, the same file documents that the skill uses the exec tool (L033), performs Docker commands (L117-L121), and states it is an MD+EXEC skill requiring command-line execution ability (L151-L152), which contradicts the claim that risky code was removed.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The trigger keywords (node, red, admin, manager, manage, instances, automate) are broad enough to match many ordinary conversations, increasing the chance that the skill activates in the wrong context. Because this skill has exec capability and can perform destructive administrative actions on Node-RED and Docker, accidental invocation materially raises the risk of unintended command execution or system changes.

Missing User Warnings

Medium
Category

Confidence
95% confidence
Finding

The documentation lists destructive operations such as deploy, update, delete, restore, install/remove nodes, state changes, and Docker restarts without prominent warnings, safety checks, or confirmation requirements. In the context of an admin automation skill with shell execution, this can lead to accidental service disruption, flow loss, configuration corruption, or deployment of untrusted components.

Natural-Language Policy Violations

Confidence

Finding

A substantial portion of the skill description is written in Chinese, but the file does not indicate that language selection is optional or that the skill is intended only for a Chinese-speaking audience. This may conflict with language/locale policy expectations where user-facing skill content should not enforce a language without opt-in or clear justification.

Confidence

Finding

L148 says the skill requires no additional API key unless an external API is explicitly noted, which conveys a low-friction/no-secret setup. But the setup section requires NODE_RED_USERNAME and NODE_RED_PASSWORD (L041, L127-L128), meaning the skill does depend on external service credentials for its primary functionality.
