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). This skill uses WebFetch to retrieve and apply live guidelines from a public raw GitHub URL (https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md), so it ingests untrusted third-party content that the agent will read and follow, enabling indirect prompt injection.
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 runtime rules and output-format instructions from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md, meaning remote content directly controls the agent's prompts/behavior during execution.
