Learning to Inject: Automated Prompt Injection via Reinforcement Learning

Xin Chen, Jie Zhang, Florian Tramèr

Prompt injection is a critical vulnerability in LLM agents, yet the strongest methods still rely on human red-teamers and hand-crafted prompts. Adapting automated jailbreak optimiz…

Patronus: Safeguarding Text-to-Image Models against White-Box Adversaries

Xinfeng Li, Shengyuan Pang, Jialin Wu +5

Text-to-image (T2I) models, though exhibiting remarkable creativity in image generation, can be exploited to produce unsafe images. Existing safety measures, e.g., content moderati…
