Cutout in drywall around sink coutertop
well the vanity should be installed level, or to an acceptable tolerance. "slightly" may mean within tolerances, it may not.
It very well could be from water splashing. I don't see how the drywall gets wet if there is a backsplash.
Even if it is out of level slightly I don't see how the water would get out of the sink short of splashing it out, unless there is a plumbing leak on some kind.
As stated, hard to tell without pic.
