NVD description
A code injection vulnerability in version 0.4.17 or later of the ChromaDB Python project allows an authenticated 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/default_tenant/databases/default_database/collections/{collection_id} if they have the UPDATE_COLLECTION permission.
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.
