I'm going through this right now.
Plenty of confusion here. I see that 8.2.15.2 is the last version on that series, and set to expire mid-year 2024. Also, that version is apparently affected per ARUBA-PSA-2023-015. So what's one to do? They recommend jumping to version 8.3.0.2.
Oh but wait, version 8.3.0.2 is not officially released in ASP. TAC told me to "wait a few days"
So here I am, just upgraded from 8.2.15.1 to 8.2.15.2, and the GUI broke. And I'm still vulnerable.
