Overview
Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the SFTP authentication process when the server is configured with an empty username and a password using the -b ':pass' flag together with -sftp. An attacker can gain unauthorized access to files by connecting to the SFTP service without providing a password. This is only exploitable if the server is started with both the empty-username basic-auth syntax and SFTP enabled.
