Security audit

Obsidian Notesmd Cli

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Obsidian note-management skill, but users should be careful because it can modify or delete local vault notes through command-line actions.

Install this only if you want an agent to operate on your Obsidian vault with notesmd-cli. Before allowing deletes, moves, or bulk edits, ask the agent to list the exact target notes first and keep a backup or sync history available.

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
97% confidence
Finding

The manifest lists activation keywords such as "via", "obsidian", "plain", and "cli", several of which are generic terms that can appear in ordinary user requests unrelated to this skill. The description also does not provide scope limits or negative examples clarifying when these keywords should or should not invoke the skill.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill explicitly documents a destructive delete command without any warning, confirmation step, dry-run guidance, or backup recommendation. In an agent context with exec capability, this increases the chance that a user request or ambiguous instruction could lead to irreversible note deletion from the local vault.

Natural-Language Policy Violations

Low
Category

Confidence
88% confidence
Finding

A substantial portion of the skill description is presented only in Chinese, while the rest of the file is in English, and there is no indication that the skill is region-specific or that users can choose their preferred language. This creates an implicit locale constraint without opt-in or justification.
