A command injection vulnerability exists in MLflow's model serving container initialization code, specifically in the install model dependencies to env() function. When deploying a model with env manager=LOCAL, MLflow reads dependency specifications from the model artifact's python env.yaml file and directly interpolates them into a shell command without sanitization. This allows an attacker to supply a malicious model artifact and achieve arbitrary command execution on systems that deploy the model. The vulnerability affects versions 3.8.0 and is fixed in version 3.8.1.
