Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain Markdown guide for using obsidian-cli with Obsidian vaults, with expected note-management powers but a delete command users should handle carefully.

Before installing, be aware that this skill can guide an agent to read, search, edit, move, and delete notes in an Obsidian vault through obsidian-cli. Confirm the active vault and exact note path before any move or delete operation, especially if the vault contains work, personal, or sensitive 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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The listed trigger keywords include generic terms such as "plain" and "obsidian," plus an ambiguous version string "1.0.0," without any constraints or negative examples. In a manifest/markdown context, these broad terms could cause unintended activation because they are not narrowly scoped to a specific action or command.

Missing User Warnings

Medium
Category

Confidence
87% confidence
Finding

The skill explicitly documents a destructive delete capability (obsidian-cli delete "path/note") without any warning, confirmation guidance, backup advice, or scope restriction. In an agent context with exec capability, this increases the chance that a user request, ambiguous instruction, or downstream prompt manipulation could cause irreversible note deletion.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

A substantial portion of the skill description is presented in Chinese, while the rest of the file is in English, and there is no indication that the user can choose their preferred language. This can amount to a language-policy issue when a skill imposes a locale or language without opt-in.
