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.

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

Findings (1)

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 93% confidence
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.
Content: No source excerpt is available for this finding.
