CVE-2026-4137

CVE-2026-4137 : In mlflow/mlflow before 3.11.0, two temp-dir creation paths expose world/group-writable permissions: get_or_create_nfs_tmp_dir() creates 0o777 and _create_model_downloading_tmp_dir() creates 0o770. This enables local attackers with access to shared NFS mounts (e.g., Databricks) to...
