There was a security issue with the v9.2.0 version released – we automatically detected quite a serious vulnerability when one of our hosting customers updated the plugin to that version and so had to report it. The offending file has been removed from v9.2.1 and is just awaiting a review by WordPress before they allow the plugin again. If you are using v9.2.0 then I would recommend removing the file in question as it provides a backdoor into your hosting account.
