I can recommend having a look at secure design patterns for LLM agents.
Simon Willison has a great post on this:

Thanks for chiming in.
I agree this is not a one-click account takeover.
But I think point 2 is broader than that. The user does not need to ask about the malicious transaction specifically. Any normal question that makes the agent fetch recent transactions could bring the attacker-controlled text into the LLM context.
