LLM Assistants Cause Cross-Team Data Leaks
A DZone Security Zone article published Feb. 18, 2026 warns that LLM assistants in multi-team organizations can inadvertently expose sensitive information when retrieval layers are not permission-aware end-to-end. It cites an example where a product manager's query surfaced Team B's answer including customer names and contact details, and notes leaks can occur during retrieval, summarization, tool traces, cached results, or shared embedding stores. Organizations should secure retrieval and embedding access controls.
