In mlflow version 2.20.3, the temporary directory used for creating Python virtual environments is assigned insecure world-writable permissions (0o777). This vulnerability allows an attacker with write access to the /tmp directory to exploit a race condition and overwrite .py files in the virtual environment, leading to arbitrary code execution. The issue is resolved in version 3.4.0.
