Researchers Propose Prismata Framework to Limit Cross‑Site Prompt Injection in Web Agents

A new research paper titled “Prismata” introduces a framework to curb cross‑site prompt injection. The work focuses on protecting web‑based agents from malicious prompt manipulation. Authors propose confinement techniques that limit injection vectors. The study analyzes how prompts can be hijacked across different sites. Experimental results suggest the approach reduces successful attacks. The paper is available on the arXiv preprint server. Researchers aim to influence future security designs for AI‑driven web agents. The community is encouraged to review and build upon the findings.
