Security audit

figma

Security checks for vulnerabilities and agentic risk

Overview

The skill is a disclosed Figma/Maton integration with some broad automation reference material, but its sensitive actions are scoped and require user approval.

Install only if you are comfortable granting Maton access to your Figma account. Review any proposed write, hosted function, trigger, or destination carefully, especially anything that forwards data continuously or uses another connected app source.

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 Figma skill manifest says trigger reference files are shared platform catalogues and explicitly states Figma is not an event source, but this file included within the skill package documents actionable Linear event types, parameters, payloads, and downstream forwarding behavior. That creates a description-behavior mismatch at the skill level because the shipped documentation exposes cross-app trigger capability beyond the manifest's stated Figma-specific scope.
