Doc Text:
A flaw was found in ChromaDB. A lack of authorization validation in the ChromaDB Python project allows any authenticated user to read, write, update, or delete data in any tenant's collection. This means an attacker can bypass intended access controls and manipulate data across different tenants, leading to unauthorized data access and modification.
