A path traversal in the SFTP provider (`SFTPHook.retrieve directory` / `SFTPOperator(operation=get)`) let a malicious or compromised remote SFTP server write files outside the configured local destination directory via crafted directory-entry names. No Airflow account is required — the attack surface is any deployment downloading directories from an untrusted SFTP server. Upgrade `apache-airflow-providers-sftp` to 5.8.1 or later.

**Name of the Vulnerable Software and Affected Versions** apache-airflow-providers-samba versions prior to 4.12.6 **Description** The `GCSToSambaOperator` in the Apache Airflow Samba provider fails to perform a containment check when joining GCS object names to the SMB destination path. This allows an attacker who can write objects into the source GCS bucket to use `../` segments in object names to resolve a write path outside the configured `destination path`, enabling the writing of files to arbitrary locations on the Samba target. **Recommendations** Upgrade apache-airflow-providers-samba to version 4.12.6 or later.
