A path traversal issue exists in the SFTP provider. A malicious or compromised remote SFTP server can write files outside the configured local destination directory by using crafted directory-entry names. This can be triggered through the `SFTPHook.retrieve directory()` function or the `SFTPOperator(operation=get)` operator. No account is required for this to occur; the risk applies to any deployment that downloads directories from an untrusted SFTP server.

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.
