This isn't true.
Edit: apparently it is now:
"This stat accounts for the following aspects of hitting: unintentional walks, hit-by-pitches, singles, doubles, triples, home runs. Stolen-bases and caught stealing numbers used to be included as well on FanGraphs, but they are now instead accounted for with the stats UBR and wSB. This way, wOBA only accounts for a player’s production at the plate."
