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 instructs the agent to fetch and use rules from the public URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md (via WebFetch) and to apply those fetched rules to drive checks and output, which exposes the agent to untrusted third‑party content that can influence behavior.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill explicitly uses WebFetch at runtime to retrieve and apply rules and output-format instructions from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md, so that external file directly controls the agent's prompts/behavior and is a required dependency.
