Risk Level: HIGHCOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
  • Indirect Prompt Injection (HIGH): The skill processes user-provided content to generate and save files, creating a significant attack surface.
  • Ingestion points: User descriptions and save path requests (SKILL.md).
  • Boundary markers: Absent; there are no instructions for the agent to validate or restrict the file paths.
  • Capability inventory: The 'mcp__mermaid__mermaid_save' tool allows writing data to the host filesystem.
  • Sanitization: Absent; the skill lacks instructions to sanitize paths or diagram content before tool execution.
  • Command Execution (MEDIUM): The skill manages external tool execution for file operations. Without strict path anchoring or validation, this capability can be abused to manipulate the host filesystem.
