PIArena: First Unified Platform for Prompt Injection Attack and Defense Evaluation
arXiv·high signal
Researchers release PIArena, a modular platform that standardizes prompt injection evaluation with plug-and-play attack and defense modules across multiple benchmarks. The paper reveals that many defenses previously reported as effective fail when tested under diverse attack conditions and across different task types. PIArena enables systematic comparison of robustness that was previously impossible due to fragmented evaluation methodologies.
