Security audit

Obsidian (Linux)

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Obsidian note-management helper, with expected access to local vault notes and no evidence of hidden or malicious behavior.

Before installing, verify that you trust the notesmd-cli Homebrew tap or AUR package. When using the skill, confirm the active vault and note path before overwrite, move, or delete commands, especially for vaults containing sensitive or work data.

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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
