Have you used or owned any sram brakes before? I don't think this looks like anything to worry about right now.
The small hole is a breather hole for the bladder behind it. It lets air out as the bladder contracts and expands. If the bladder had torn, you'd probably see quite a lot of fluid coming out the small hole.
But the amount that has come out doesn't look like anything to worry about and the fact that the bike is brand new suggests that its unlikely both bladders are ruptured. More likely that they have had a slightly heavy handed(enough pressure on the syringe can force a tiny amount of fluid past the bladder) bleed and haven't been wiped down properly.
@farewell fwiw I have sram brakes on all my bikes, every now and then a tiny amount of fluid appears at the air hole, it's usually after uplift riding with lots of hard braking. I wipe it away and theres no problems.
Wipe it off and I doubt you'll see it return any time soon. To me, its quite normal with sram brakes.
