CVE-2026-2614: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in mlflow mlflow/mlflow
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.
AI Analysis
Technical Summary
The vulnerability exists in the _create_model_version() handler in mlflow/server/handlers.py in mlflow versions up to 3.9.0. An attacker can include the tag mlflow.prompt.is_prompt in a CreateModelVersion request to bypass source path validation, enabling storage of arbitrary local filesystem paths as the model version source. Subsequently, the get_model_version_artifact_handler() serves files from this source without verifying the prompt status, allowing unauthorized file reads. This results in a complete confidentiality compromise. The issue is resolved in mlflow version 3.10.0.
Potential Impact
An unauthenticated remote attacker can read arbitrary files from the server's filesystem, leading to a total confidentiality breach of potentially sensitive data stored on the affected system. There is no impact on integrity or availability reported.
Mitigation Recommendations
A fix is available in mlflow version 3.10.0. Users should upgrade to version 3.10.0 or later to remediate this vulnerability. Patch status is confirmed by the vendor advisory. No alternative mitigations are indicated.
