New JPPO attacks exploit vision-language models by optimizing pixels and prompts

Researchers have developed a new adversarial framework called Joint Pixel-Prompt Optimization (JPPO) that targets vision-language models (VLMs). Unlike previous methods that focused on image perturbations, JPPO jointly optimizes both image pixels and user-visible prompts to amplify resource exhaustion attacks. This approach significantly increases latency and energy consumption in models like Qwen2.5-VL-7B and BLIP-2, revealing potential security vulnerabilities in current VLM serving defenses. AI

IMPACT Highlights potential security vulnerabilities in multimodal AI deployments, necessitating cost-aware robustness evaluations.

    Multimodal Resource-Exhaustion Attacks on Vision-Language Models via Joint Pixel-Prompt Optimization

    arXiv:2609.05889v1 Announce Type: new Abstract: Resource-exhaustion attacks against autoregressive vision-language models (VLMs) typically assume unimodal threat models, treating the image branch as the primary optimization surface while holding user-visible prompts fixed. Even r…
