Re-install security update after CU-update?

Hello all, At this moment our server is running Exchange 2019 CU12 with the June security update installed. This week we will install CU13. Do we have to install the June security update again? ...

    The June security updates will be similar for each CU, but they are specific to the CU version, so yes you should install the SU for CU13 after you've installed CU13.
