uNotes: Building Study Guides

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently reads selected uNotes documents to create study materials in chat, with no write tools, persistence, or hidden execution behavior found.

Before installing, understand that the skill can read selected uNotes document text to generate study materials in chat. Confirm the selected document when search is used, especially if your uNotes library contains private or unrelated notes.

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’s invocation description uses broad phrases like 'summarize these notes', 'make a cheat sheet', and 'help me study for my exam', which can overlap with many ordinary study-related requests. This can cause over-triggering, leading the agent to activate the skill in situations where the user did not intend to use uNotes content, potentially causing unnecessary access to connected document data or misrouting user requests.
