AI agents face new trust boundary threats beyond user prompts

By PulseAugur Editorial · [1 sources] ·

Modern AI agents face complex trust issues because they process information from multiple sources beyond just user prompts, including retrieved documents, tool outputs, and internal data. This introduces new attack vectors where malicious text embedded in these sources can bypass traditional system prompt safeguards. A more effective approach involves modeling trust boundaries, assessing what information can influence specific agent actions, and implementing granular policies to prevent unauthorized side effects. AI
