Security audit

Homeassistant Toolkit

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Home Assistant reference skill that only prints static documentation, with no evidence of credential access, network calls, persistence, or destructive behavior.

Review whether you want such a generic reference skill installed, since its routing description could be narrowed. From the inspected artifacts, it appears safe as a static documentation helper and does not need credentials or elevated access.

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

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The skill description is broad and generic enough to overlap with normal user requests for Home Assistant help, increasing the chance the platform invokes this skill unexpectedly. Over-broad routing can cause unintended skill activation and may let the skill intercept requests outside its narrowly intended scope, which is a security and safety boundary issue even though this specific skill appears read-only.
