New image-based prompt injection attack targets multimodal AI models

Security researchers have developed a new image-based prompt injection attack that can manipulate how multimodal AI systems interpret user instructions without modifying the original text prompt, potentially expanding security risks for AI agents and vision-language systems. In a research paper published this week, researchers from Xidian University described a technique called “CrossMPI,” which uses nearly imperceptible image perturbations to alter how large vision-language models (LVLMs) proce
