MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.70). The skill directly ingests untrusted third‑party SendGrid webhook POSTs (see /webhooks/sendgrid handlers in examples/express/src/index.js, examples/fastapi/main.py, and examples/nextjs/app/webhooks/sendgrid/route.ts), parsing JSON event payloads and branching on event types to drive processing (e.g., unsubscribe, bounce, click), so externally provided content can materially influence behavior.
