Summary

Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. Prior to version 2.2.3, the upload status SSE implementation on /uploadStatus publishes global upload state to any authenticated listener and includes file_id values that are not scoped to the requesting user. This issue has been patched in version 2.2.3.
