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). This skill directly ingests GitHub webhook payloads (POST /webhooks/github in examples/express/src/index.js, examples/fastapi/main.py, and examples/nextjs/app/webhooks/github/route.ts) which contain user-generated/untrusted content (issues, PRs, comments) that the agent parses and is intended to drive actions (bot responses, CI/CD, auto-merge) so third-party content can materially influence behavior.
