What it is

xiaoheiFS is a self-hosted financial and operational system for cloud service businesses. In versions up to and including 0.3.15, the standard plugin system allows admins to upload a ZIP file containing a binary and a `manifest.json`. The server trusts the `binaries` field in the manifest and executes the specified file without any validation of its contents or behavior, leading to Remote Code Execution (RCE). Version 0.4.0 fixes the issue.
