xiaoheiFS Vulnerable to RCE via Unrestricted Plugin Installation (Manifest Manipulation)

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.
