Web stats are insecure and need updating
It's unclear if the stats stuff even gets used, as it's not mentioned much in the old Symbiosis docs.
However, some time ago it was supposed to be disabled by default, but that's not the case, so it's automatically generated for each site at /stats, and doesn't require any auth at all.
This should either be secured properly, or replaced with something a bit more up to date, like goaccess which has a package and is realtime.
