CVE-2025-15379: Lfprojects MLflow

Critical severity, CVSS 10.0. EPSS: 2.4% chance of exploitation in the next 30 days.

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 3.8.2.

Affected products

• Lfprojects MLflow: from 3.8.0, before 3.8.1 (fixed in 3.8.1)
