Risk Level: MEDIUM

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). The skill explicitly ingests and processes webhook POSTs from external providers (Resend, Postmark, SES via SNS, SendGrid, Mailgun) and even instructs fetching the SNS SubscribeURL, meaning untrusted third-party/user-generated content is read and can directly drive actions like suppressions, state changes, and outbound webhooks.
