Mitigating Database Leakage in RAG Systems with Keyword-Grounded Fact Substitution
arXiv cs.CL — Computation and Language
Factual evidence
What the source reports
Researchers introduced KFS-RAG, a technique using keyword-grounded fact substitution to prevent prompt injection data leakage in RAG.
Open sourceOneBench interpretation
Institutional assessment
So what
Context exfiltration via prompt injection is a top security blocker for deploying G-SIB RAG systems over sensitive database environments.
Do what
Ask your AI security and red-teaming leads to benchmark KFS-RAG against current context-sanitization filters for high-risk search pipelines.
