MIRAGE: Stealthy Visual Prompt Injection for Vulnerability Detection in Web Agents

Read the original on arXiv AI →

MIRAGE is a visual indirect prompt injection framework that targets multimodal large language model (MLLM)-based web agents. It operates under realistic constraints where an attacker controls only a semantically legitimate, spatially confined region such as an ad slot or widget. Using diffusion models and a robust optimization technique, MIRAGE generates perceptually benign adversarial images confined to the attacker’s boundaries, enabling next‑action hijacking while remaining stealthy.

Breaking the weakest link to evade vision language models

The paper investigates how Vision Language Models (VLMs) can be fooled by small, human‑imperceptible changes to images. It introduces a gradient‑based attack that targets only the vision encoder, reducing computational cost while still effectively disrupting both untargeted and targeted multimodal alignment. Experiments on open‑source VLMs such as Qwen2.5‑VL, Granite‑Vision, FastVLM, and Phi‑3.5‑Vision demonstrate that these perturbations can significantly alter the models’ textual outputs.
