It is not unauthenticated remote code execution.\nRH AI products ship a vulnerable chromadb version but do not expose the Chroma FastAPI API as the default product surface. RHOAI AutoRAG uses Llama Stack with Milvus/pgvector; RHEL AI bootc images include chromadb as a library dependency, not a network-facing Chroma server. Without a customer or misconfiguration that runs and exposes the Chroma Python server to untrusted users, the upstream attack path is not reachable.\nUpstream CVSS 9.4 Critical assumes network access to Chroma\u2019s API with exploitable permissions.
