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's SKILL.md explicitly instructs the agent to fetch live guidelines via WebFetch from a public URL (https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md), meaning untrusted third-party content is ingested and used to drive rules and output behavior.
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 rules and output-format instructions from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md, which directly controls the agent's prompts/behavior and is required for each review.
