CVE-2023-22466: Tokio reject_remote_clients configuration may get dropped when creating a Windows named pipe
When configuring a Windows named pipe server, setting pipe_mode will reset reject_remote_clients to false. If the application has previously configured reject_remote_clients to true, this effectively undoes the configuration. This also applies if reject_remote_clients is not explicitly set as this is the default configuration and is cleared by calling pipe_mode.
Remote clients may only access the named pipe if the named pipe’s associated path is accessible via a publically shared folder (SMB).
