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

• Third-party content exposure detected (high risk: 0.90). The skill's SKILL.md explicitly lets the agent fetch and read external FormCan data (e.g., "Get Submission" returns submission data including form responses, attachments" and the "membrane request CONNECTION_ID /path/to/endpoint" proxy) which ingests user-generated, untrusted content from a third-party service that can influence subsequent actions.
