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). The SKILL.md explicitly requires fetching and using live guidelines from the public URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md (via WebFetch) and then applying those rules to drive checks and output, which exposes the agent to untrusted third‑party content that can change behavior.
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 and using at runtime the guidelines from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md, and that fetched content contains the rules and output-format instructions which directly control the agent's behavior.
