Hi @Dua97
You should immediately upgrade to a newer release:
And you should migrate away from H2 if you are using Metabase in production:

Open the XLSX file in Notepad to see the stacktrace contents of the file, or look in Metabase > Admin > Troubleshooting > Logs.

Does the upgrade have some Metabase Downtime?

@Dua97 You should stop everything you are doing and upgrade immediately. Doesn't matter if there's downtime. In case you somehow never heard of Log4j vulnerability, then try searching the internet.
Just like upgrading anything, there is downtime while you are upgrading. Always backup first.
