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: 0.70). The skill's middleware explicitly ingests and interprets arbitrary incoming HTTP request data (e.g., req.request.headers, path_params, query_params as shown in SKILL.md and the Reference Implementation) and uses it to decide actions (respond vs continue), which means untrusted third-party request content can materially influence control flow and thus could enable indirect prompt injection.
