Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). The skill receives and processes untrusted, user-generated email content when "Postmark ... POST[s] parsed email data" to your webhook (SKILL.md "Receive JSON" and the Webhook Payload / references/payload-structure.md), and the workflow explicitly parses TextBody/StrippedTextReply, attachments, and MailboxHash to route, create tickets, run "command processing", and take follow-up actions—allowing third-party content to materially influence behavior.
