What is CVE-2025-15379?
CVE-2025-15379 is a critical command injection vulnerability in Lfprojects Mlflow, published on 30 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
