Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.80). The skill instructs the agent to fetch and read public web resources (e.g., WebFetch loading https://modelcontextprotocol.io/llms-full.txt and raw GitHub READMEs plus ad-hoc web search), which are public third-party sources that may contain untrusted or user-generated content the agent will read and interpret, enabling indirect prompt injection.
