Title
Arbitrary File Read via Prompt Tag Source Validation Bypass in mlflow/mlflow
Summary
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 version source. The `get_model_version_artifact_handler()` function later uses this source to serve files without verifying the model version's prompt status, leading to a complete confidentiality compromise. This issue is fixed in version 3.10.0.

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 version source. The `get_model_version_artifact_handler()` function later uses this source to serve files without verifying the model version\u0027s prompt status, leading to a complete confidentiality compromise. This issue is fixed in version 3.10.0."

An unauthenticated remote attacker can exploit a vulnerability in the `_create_model_version()` handler by including a specific tag, `mlflow.prompt.is_prompt`, in a `CreateModelVersion` request. This bypasses source path validation, allowing the attacker to specify an arbitrary local filesystem path as the model version source. Subsequently, the `get_model_version_artifact_handler()` function serves files from this unverified source, leading to the disclosure of arbitrary files from the server\u0027s filesystem and a complete confidentiality compromise."

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 version source. The `get_model_version_artifact_handler()` function later uses this source to serve files without verifying the model version\u0027s prompt status, leading to a complete confidentiality compromise. This issue is fixed in version 3.10.0."
