DualView: Preventing Indirect Prompt Injection in Personal AI Agents
Quick summary
arXiv:2607.03821v2 Announce Type: replace-cross Abstract: Personal AI agents that run on the user's local machine automate daily tasks including web search, email, and file management. Their access to computer resources, including the network, file system, and shell, exposes them to indirect prompt injection (IPI) attacks. Prior Dual LLM defenses block IPI by replacing untrusted data with symbols that the agent can reference but not read. However, they track untrusted data only inside the agent's context, so when the agent saves and later rereads untrusted data, that data, possibly an attacker

Why it matters
“DualView: Preventing Indirect Prompt Injection in Personal AI Agents” shows why AI risk cannot be reduced to answer accuracy. Access controls, logging, human approval and incident response need to be designed into the workflow from the start.
