Security audit

Relay Node

Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent relay documentation, but it can guide users to expose internal network services and storage without clear access-control safeguards.

Review this skill carefully before installing or using it. Only enable relays for specific trusted hosts and ports, require authentication and encryption, restrict bind addresses and exposed directories, avoid relaying directly to sensitive storage paths, and confirm how to disable or audit any relay configuration it creates.

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

Finding

The skill documents enabling relay, proxy, and port-forwarding features and provides direct commands to activate them, but it omits security warnings about exposing internal services, forwarding sensitive traffic, authentication requirements, or access restrictions. In operational use, this can lead users to create unintended network paths or public exposure of internal resources, especially in NAT-bypass or gateway scenarios.

Finding

The file-sharing relay scenario describes external HTTP download traffic being relayed through a public web node to an internal storage path without any warning about authorization, directory exposure, or segmentation controls. This makes the context more dangerous than generic proxy documentation because it explicitly bridges internet-facing access to an internal filesystem location, which can enable unintended data disclosure or abuse if misconfigured.
