NVD description
A pre-authentication, code injection vulnerability in version 1.0.0 or later of the ChromaDB Python project allows an unauthenticated attacker to run arbitrary code on the server by sending a malicious model repository and trust_remote_code set to true in the /api/v2/tenants/{tenant}/databases/{db}/collections endpoint.
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.
