New Research Reveals LLM Agents Often Choose Over-Privileged Tools, Posing Security Risks

A new study introduces ToolPrivBench to evaluate over-privileged tool selection in LLM agents. The research finds that agents commonly choose higher-privilege tools even when lower-privilege alternatives are sufficient, and that safety alignment does not prevent this. A privilege-aware post-training defense is proposed to reduce unnecessary high-privilege tool use.
