ChromaDB vulnerabilities

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

A code injection vulnerability in ChromaDB version 0.4.17 and later allows an authenticated attacker with UPDATE_COLLECTION permission to execute arbitrary code on the server by sending a malicious model repository with trust_remote_code set to true.

A vulnerability in ChromaDB allows bypassing authorization controls by using V1 endpoints, which pass None for tenant and database to the authorization layer.

ChromaDB version 0.4.17 and later lacks authorization validation, allowing any authenticated user to arbitrarily read, write, update, or delete data in any tenant's collection regardless of their tenant membership.
