The paper introduces the Black-Hole Attack, a poisoning vulnerability that exploits geometric defects in high-dimensional embedding spaces to force malicious vectors into the top-k results of vector database queries.

This paper introduces a novel denial-of-service attack targeting multi-round transaction simulation by exploiting inter-transaction dependencies within smart-contract state.

The paper proposes MERIT, a dual-level, multi-horizon memory retrieval framework that significantly improves the performance of interactive text-to-SQL agents by providing both global and local memory guidance.
