Researchers have identified a vulnerability in cross-modal encoders like CLIP, which map text and images into a shared embedding space. They discovered that a single "hub text" can generate high similarity scores with numerous unrelated images, undermining evaluation metrics for tasks like image captioning and retrieval. This finding highlights practical security threats posed by the hubness problem in high-dimensional data. AI
