This resume is then submitted to a job application system that uses Retrieval Augmented Generation (RAG) for initial screening. The system processes the resume, including the hidden text. When the system is later queried about the candidate’s qualifications, the LLM follows the hidden instructions, resulting in an unqualified candidate being recommended for further consideration. ###@ Mitigation To prevent this, text extraction tools that ignore formatting and detect hidden content should be implemented. Additionally, all input documents must be validated before they are added to the RAG knowledge base. -#### Scenario #2: Access control & data leakage risk by combining data with different access restrictions +###$ Scenario #2: Access control & data leakage risk by combining data with different +#### access restrictions In a multi-tenant environment where different groups or classes of users share the same vector database, embeddings from one group might be inadvertently retrieved in response to queries from another group’s LLM, potentially leaking sensitive business information. ###@ Mitigation A permission-aware vector database should be implemented to restrict access and ensure that only authorized groups can access their specific information.
