  A first measurement of neutrinos from the CNO fusion cycle in the Sun would
allow a resolution to the current solar metallicity problem. Detection of these
low-energy neutrinos requires a low-threshold detector, while discrimination
from radioactive backgrounds in the region of interest is significantly
enhanced via directional sensitivity. This combination can be achieved in a
water-based liquid scintillator target, which offers enhanced energy resolution
beyond a standard water Cherenkov detector. We study the sensitivity of such a
detector to CNO neutrinos under various detector and background scenarios, and
draw conclusions about the requirements for such a detector to successfully
measure the CNO neutrino flux. A detector designed to measure CNO neutrinos
could also achieve a few-percent measurement of pep neutrinos.
