A new paper introduces Prismata, a confinement layer that prevents cross-site prompt injection attacks on LLM agents by validating instructions from webpages before executing actions. The system imple…
A group at UC Berkeley warns that prompt injection is becoming the cross-site scripting (XSS) of the web agent era, calling the vulnerability Cross-Site Prompting (XSP). Their system, Prismata, sits b…
Researchers introduced Prismata, a defense against cross-site prompt injection in autonomous web agents that enforces contextual least privilege by dynamically deriving permission labels for page cont…
Prismata introduces a new security standard for autonomous web agents by enforcing contextual least privilege, protecting them from prompt injection attacks without requiring developer intervention. T…
Autonomous web agents face old security threats like prompt injection, and a new defense called Prismata aims to protect them using contextual least privilege. Prismata dynamically labels web content …
