Why it matters
RAG data leakage lets authenticated users retrieve information they should not access without any malware or account compromise, making it a silent enterprise exposure that traditional security dashboards miss.
A vendor guide from LangProtect explains how Retrieval-Augmented Generation (RAG) systems can leak sensitive enterprise data, using an illustrative case of a healthcare AI assistant that returned document excerpts across business units because a shared vector index was queried before document permissions were evaluated. The article outlines the mechanism of RAG data leakage and references academic work on adaptively attacking RAG systems to exfiltrate private knowledge bases.
