Security audit

Obsidian Markdown (kepano)

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only Obsidian Markdown helper with a broad trigger phrase but no code, credentials, persistence, or hidden behavior.

Installers should understand that this skill may be invoked when discussing generic Markdown concepts such as tags or frontmatter, but its behavior is limited to providing Obsidian Markdown formatting guidance and does not grant runtime authority.

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 description says to use the skill when working with .md files in Obsidian or when the user mentions broad terms like 'tags', 'frontmatter', or 'embeds'. Some of these terms are generic and could trigger the skill for ordinary markdown or unrelated contexts without clear exclusion conditions.
