N8N Docker Monitor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed n8n Docker monitoring helper; its Docker and log access need normal care but no hidden or malicious behavior was found.

Install only where the agent is intended to inspect the local n8n Docker environment. Be aware that recent n8n logs may include sensitive operational details, so use it with appropriate Docker access and on trusted hosts.

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

Low

Category: Not specified by scanner
Confidence: 86% confidence
Finding: The natural-language description is written only in Portuguese ("Monitora o n8n e envia alertas") with no indication that the skill is region-specific or that users can choose their preferred language. This can violate language or locale policy when a skill implicitly enforces a specific language without opt-in.
Content: No source excerpt is available for this finding.
