AI database security flaw risks exposing wrong tenant data

A critical AI database vulnerability arises not from syntax errors, but from queries that return correct-looking data while subtly exposing the wrong tenant's information. To enhance security, tenant scope should be managed by authentication systems rather than prompt instructions, which models can overlook. Implementing stricter database policies, such as deriving scope from authentication, using read-only scoped roles, and requiring explicit authorization for cross-tenant reporting, can prevent such data leaks.
