obsidian

Security checks for vulnerabilities and agentic risk

Overview

This Obsidian helper is a coherent CLI reference for managing local vault notes, with disclosed read, write, move, and delete capabilities.

Install this only if you want an agent to operate on your Obsidian vaults. For delete, move, bulk edit, plugin, or eval actions, give exact vault and path instructions and keep backups or version control for important notes.

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 explicitly includes commands to create, append, prepend, move, and delete notes, but it does not warn that these actions modify or permanently remove user vault data. In an agent setting, that omission increases the chance of unintended destructive operations, especially because Obsidian vaults often contain primary notes, tasks, and attachments across multiple vaults.
