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: 0.85). The skill’s runtime “query”/“search” commands fetch and cache web specifications from public sources (e.g., WHATWG/W3C/IETF/TC39 spec URLs) and then ingest the fetched section text into the agent’s LLM context as markdown/JSON, which is outsider-authored free text from public web content.
