The Apache Airflow Samba provider's
GCSToSambaOperatorjoined GCS object names to the SMB destination path without a containment check, so an object named with../segments resolved a write path outside the configureddestination_path. An attacker able to write objects into the source GCS bucket — typically an external data producer distinct from the trusted DAG author — could write files to arbitrary locations on the Samba target when the operator ran. Upgrade apache-airflow-providers-samba to 4.12.6 or later, which validates the resolved destination stays withindestination_path. - References
