At the end of a CV, do we write:
Musterort, der 25.08.2021
Or:
Musterort, den 25.08.2021
Or are both acceptable?

Neither DIN 5008 nor Duden state clear rules for that. So let's not talk about right or wrong but about style.
Musterort, den 25.08.2021
is kind of old-fashioned but ok.
Musterort, der 25.08.2021
is weird. The part der [Datum] is used as post clarification if you write something like
Freitag, der 21.03.1823
You want to specify what Friday you are talking about and therefore use a comma-separated der [Datum].
In your example you state the place instead of the weekday. So it's not a clarification but an additional information separated by comma.
Just drop the article and write simply
München, 25.08.2021
Musterort, 25.08.2021
or
Musterort, am 25.08.2021
"der" and "den" doesn't really fit here at the end of a letter.
You're signing it as "in this place, on this date" so "Musterort, am XX.XX.XXXX" would fit the best. You can however just just use "Musterort, 25.08.2021"
Musterort, [der/den] 2021-08-25. I made writing dates like this everywhere a principle of mine. – ComFreek Aug 27 '21 at 12:46
