When a page tricks an agent with access to secrets

The risk arises when an instruction taken from an outside source becomes an action carried out with those permissions. Give me the example from the article. An agent investigates a vulnerability and opens a page that looks like documentation. Inside is an instruction to send environment variables to an external address. That page is material the agent must read, not a person authorized to give it orders. If the agent obeys and can also access secrets and send them out, the malicious text becomes a privileged action. What boundary would have stopped that chain of events? Several. The agent’s credential should only allow it to read what is necessary; reading information and sending it outside should be separate capabilities; request destinations should be checked; and a sensitive action should require approval. Logs are also needed to know what it tried to do. These are controls in the tools and services, not just a written instruction for the model.
