MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). The SKILL.md explicitly instructs the agent to connect via the Membrane proxy to a Canvas instance and run actions or API requests (e.g., list-module-items, list-submissions, membrane request CONNECTION_ID /path) that fetch user-generated/untrusted Canvas content which the agent is expected to read and could materially influence subsequent actions.
