missive

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

• Third-party content exposure detected (high risk: 0.80). This skill instructs the agent to use the Membrane CLI to connect to Missive and run actions (e.g., "membrane action list" / "membrane action run") that fetch Conversations/Messages/Contacts—user-generated content from external accounts—which the agent is expected to read and act on, so untrusted third-party content could carry indirect instructions.
