Firm N8n Bridge Pack

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed bridge for importing and exporting OpenClaw and n8n workflow files, with no bundled executable code or hidden persistence found.

Before installing, confirm you trust the required mcp-openclaw-extensions provider and review exported or imported workflow JSON before using it in automation. The French warning should be translated or duplicated in English for clarity, but it is not a security blocker.

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

Natural-Language Policy Violations

Finding
Line L24 presents a user-facing warning entirely in French, while the rest of the skill documentation is in English. This creates an implicit language constraint without user opt-in or any documented reason for the locale choice, which matches the language/locale policy violation criteria.
