Retrieval-augmented generation (RAG) systems, while powerful for grounding LLMs in specific data, introduce significant security vulnerabilities. The core issue is that RAG systems treat retrieved documents as untrusted input, making them susceptible to indirect prompt injection where malicious instructions are embedded within documents. Attackers can exploit this by poisoning the knowledge base, bypassing access controls to leak sensitive data, or directly injecting harmful commands that the LLM cannot distinguish from legitimate data. To mitigate these risks, developers must enforce access controls at retrieval time, treat retrieved content as untrusted, contain the actions triggered by RAG outputs, carefully curate indexed data, and monitor for suspicious activity.
