Risk Level: SAFEPROMPT_INJECTION
Full Analysis
  • Indirect Prompt Injection (LOW): The skill handles untrusted data through email templates and batch message content without providing safety boundaries or sanitization guidance.
  • Ingestion points: Ingestion occurs through the POSTMARK_GET_TEMPLATE tool which retrieves HTML/Text bodies, and the TemplateModel parameter which accepts user-supplied variables.
  • Boundary markers: Absent. The instructions do not direct the agent to treat template content as untrusted data or to ignore embedded instructions.
  • Capability inventory: High-impact capabilities include mass email delivery (POSTMARK_SEND_BATCH_WITH_TEMPLATES) and server configuration modification (POSTMARK_EDIT_SERVER).
  • Sanitization: Absent. No requirement for input validation or escaping of template content is specified.
