PatchTheCVECVE-2026-2614: A vulnerability in the `_create_model_version()` handler of `mlflow/server/handlers.py` in mlflow/mlflow versi
CVE-2026-2614 is a high-severity flaw (CVSS 7.5) affecting mlflow. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A vulnerability in the `_create_model_version()` handler of `mlflow/server/handlers.py` in mlflow/mlflow versions 3.9.0 and earlier allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem. The issue arises when a `CreateModelVersion` request includes the tag `mlflow.prompt.is_prompt`, which bypasses source path validation. This enables an attacker to store an arbitrary local filesystem path as the model vers
