arXiv:2607.01276v1 Announce Type: cross Abstract: Embedding models are essential components of modern Information Retrieval (IR) systems, yet they are typically hidden behind APIs. Recent works have shown that dense IR system can lead to security vulnerabilities such as embedding inversion attacks. However, such attacks usually require that the attacker knows the embedding model for the attack to be applicable. In this paper, we study IR systems under a black-box setting in which the adversary observes only the unordered set of retrieved documents, without ranking or similarity scores. We demo
The proliferation of powerful embedding models and their deployment behind opaque APIs creates new attack surfaces, making research into their vulnerabilities timely and critical.
Understanding and mitigating black-box inference attacks on AI systems is crucial for data privacy, model security, and the integrity of information retrieval systems built on such foundations.
This research reveals newattack vectors against widely used embedding models even without direct model access, complicating the security landscape for AI-powered services.
