In a RAG assistant, a vector index may bypass the original system's permission checks, causing unauthorized users to silently obtain sensitive documents through semantic retrieval, and if personal data is involved, this may also constitute a compliance issue.

UnverifiedThe root cause of normalization inconsistency vulnerabilities typically lies in the fact that the permission check and data access stages each receive and process user input separately, without sanitizing or normalizing the input at a unified entry point.72% similarUnverifiedIn practice, this requires a clear split in the pipeline from enterprise data lake to RAG: the vector index stays ignorant of identity, a thin, fast, synchronous authorization layer is retained to query the governance system directly on each retrieval request, scoped to the candidate documents returned by vector search, and monitored and alerted separately.72% similarUnverifiedMost enterprise RAG systems bake access control into the vector index at the embedding stage, treating permissions like content freshness, so that revoked access rights can still return results through retrieval, forming a security lag window.71% similarUnverifiedFor structured business rules, relying solely on semantic retrieval (RAG) is often unreliable, and it is more appropriate to use rule engines or structured databases for management and validation.71% similarUnverifiedIn a legal-scenario RAG system, when the retrieved results are insufficient to support an answer, the system must explicitly refuse to answer; this is a core function, not a system limitation.70% similar
