Prior to 12.23Q4.5, Nexkey allows external apps using tokens issued by administrators and moderators to call admin APIs. This allows malicious third-party apps to perform operations such as updating server settings, as well as compromise object storage and email server credentials. This issue has been patched in 12.23Q4.5.
