W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). This skill explicitly fetches and processes arbitrary external URLs and user-supplied messages—see SKILL.md "Quick Start: Fetch API" and references/fetch-api.md (fetchWithRetry, fetchParallel, proxy patterns) and templates/websocket-handler.ts (parsing and acting on WebSocket client messages)—so untrusted third-party content is ingested and can directly influence runtime behavior (proxying, JSON parsing, broadcasting), enabling indirect prompt injection.
