Security audit

YouTube

Security checks for vulnerabilities and agentic risk

Overview

This YouTube skill is a clearly documented Maton API integration with disclosed OAuth, write-operation, and automation risks guarded by user-approval instructions.

Before installing, understand that this skill can act on your connected YouTube account and can create persistent Maton automations if you approve them. Use the read/list flows first, confirm the exact account and resource before writes, and avoid raw API-key mode unless the CLI cannot be used.

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

This markdown file includes a write example that sets "defaultLanguage": "en" in the playlist creation payload. Although the surrounding text notes that the value is illustrative, the example still defaults to a specific language/locale, which can conflict with the policy against forcing a language without user opt-in.
