Detailsinfo A vulnerability was found in MLflow up to 3.8.x. It has been declared as critical. Affected by this vulnerability is the function extract_archive_to_dir of the file mlflow/pyfunc/dbconnect_artifact_cache.py. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-29. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is: A path traversal vulnerability exists in the `extract_archive_to_dir` function within the `mlflow/pyfunc/dbconnect_artifact_cache.py` file of the mlflow/mlflow repository. This vulnerability, present in versions before v3.7.0, arises due to the lack of validation of tar member paths during extraction.
