Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). This SKILL.md explicitly instructs running "npx -y ytsubs '(... URL or ID)'" to fetch YouTube video metadata, descriptions, and transcripts (public, user-generated content) which the agent is expected to read/save and could therefore contain instructions that influence subsequent actions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill runs "npx -y ytsubs" at runtime, which fetches and executes the remote npm package (e.g. https://registry.npmjs.org/ytsubs or https://www.npmjs.com/package/ytsubs), so it executes remote code fetched at runtime and is a required dependency.
