Threats affecting pkg:github/chromadb

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.

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.

CVE-2026-45831 is a high-severity authorization vulnerability in the ChromaDB Python project affecting version 0.5.0. The SimpleRBACAuthorizationProvider does not verify the tenant, database, or collection context when checking user permissions, allowing users to perform unauthorized cross-tenant actions.

CVE-2026-8828 is a high-severity vulnerability in ChromaDB Rust project version 1.0.0 that allows any authenticated user to bypass authorization controls. This flaw enables users to read, write, update, or delete data in any tenant's collection regardless of their tenant membership. The vulnerability arises from a lack of authorization validation related to user-controlled keys.

A lack of authorization validation in version 0.4.17 or later of the ChromaDB Python project allows any authenticated users to arbitrarily read, write, update, or delete data in any tenant's collection regardless of which tenant they belong to.

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.
