  A group $G$ has $F\mathcal C_n$ if every action on a $n$-dimensional
$\mathrm{CAT}(0)$ cube complex has a global fixed point. This provides a
natural stratification between Serre's $FA$ and Kazhdan's $(T)$. For every $n$,
we show that random groups in the plain words density model have $F\mathcal
C_n$ with overwhelming probability. The same result holds for random groups in
the reduced words density model assuming there are sufficiently many
generators. These are the first examples of cubulated hyperbolic groups with
$F\mathcal C_n$ for $n$ arbitrarily large.
