Cross-Origin Request Blocked

So I built riz and riz-ui in release mode, started riz-api and riz-ui with the appropriate env variable and now the browser gives me the following error.

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8080/v1/rooms. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 400.

Is it something that depends on how the users setup their server or a bug that should be fixed on Riz’s side?
