This enables interaction with the MLflow Assistant running on a victim's local machine, bypassing loopback-only restrictions. Consequently, an attacker can modify the Assistant's configuration to gain full access, leading to the execution of arbitrary commands via the Claude Code sub-agent. mlflow: MLflow: Arbitrary Code Execution via Improper Origin Validation No Red Hat products ship the affected version of mlflow.
