Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 1.00). The skill's SKILL.md explicitly requires fetching and using the live guidelines from the public URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md via WebFetch, and the agent must read and apply those fetched rules (including output-format instructions), so untrusted third-party content could influence its actions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 1.00). The skill explicitly instructs fetching https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md at runtime via WebFetch and states the fetched document "contains all the rules and output format instructions," meaning the remote content directly controls prompts/instructions and is a required dependency.
