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 uses WebFetch to retrieve and then apply rules from a public URL (https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md), meaning the agent ingests and interprets open third-party content that could contain injected instructions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill explicitly WebFetches the runtime rules from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md on each review, and that fetched content directly controls the agent's checking rules and output format and is required for operation, so it presents a high-risk external instruction dependency.
