Name of the Vulnerable Software and Affected Versions apache-airflow-providers-sftp versions prior to 5.8.1

Description 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.

Recommendations Upgrade to version 5.8.1 or later.
