Log4j vulnerability

I tried to find information about Nuki and log4j. Can someone answer wether Nuki uses it or not?

If you’d ask customer support, they would tell you:

We analyzed all our systems and services if they are affected and identified the ones we had to update. These updates were already applied. There are currently no further issues in this regard. There was no intrusion into one of our systems and no customer data was ever exposed.
