The chat route directly invokes agent.chat(request.message), allowing no-auth or wrong-bearer requests to trigger agents. This potentially allows unauthenticated clients to access agents configured with tools, private context, memory, API integrations, or cost-bearing model calls.</p> criticaladvisory
