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.md explicitly instructs the agent to "Fetch fresh guidelines" via WebFetch from the public URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and to read and apply those fetched rules and output-format instructions, so untrusted third-party content can directly influence the agent's checks and actions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 1.00). The skill explicitly fetches runtime guidelines from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and uses the fetched content as the rules/instructions that directly control the agent's review behavior, making it a required external runtime instruction source.
