Prompt injection attacks on AI agents are a structural vulnerability that cannot be solved by simply instructing the agent on what not to do. Instead of relying on allowlists or belief systems, security should focus on limiting the agent's access to tools and data by effect, not by name. Tracking the provenance of information and removing unnecessary permissions are key to building more secure AI agents. AI

IMPACT Highlights critical security flaws in AI agents, emphasizing the need for robust access controls and provenance tracking to prevent misuse.
