Why it matters
Confused deputy risks require defenders to enforce authorization at privileged action boundaries rather than rely on an agent to distinguish trusted instructions from untrusted content.
Confused deputy attacks occur when AI agents interpret attacker-controlled emails, documents, issues, or tool responses as instructions and exercise privileges the content's author does not possess.
