NVD description
All V1 collection-level endpoints in ChromaDB's Python project pass None for the tenant and database to the authorization layer, allowing attackers to bypass authorization controls by using the V1 endpoints.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep Chroma off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
