The Space Shuttle and the Soviet/Russian Buran have launched vertically, and their wings were exposed to the full load of aerodynamic forces during the launch. Stability may come from many factors, but the location of the wings near the bottom of the whole launch assembly certainly must have helped.
On the other hand, the X-37 was launched into space at the top of a long rocket where lift forces could have presented a big stability challenge, so it was launched protected from aerodynamic forces inside a fairing.
Are the US shuttle and Buran the only space planes to launch vertically to orbit with wings exposed?
This one doesn't count, as it didn't go into orbit, but it deserves an honorable mention. From the question ISRO's space plane on top of of a rocket - how unstable was it?, here are some photos of ISRO's RLV-TD.
In this case it is really a passive payload and does not participate in the launch. According to this answer:
From what I have read in journal papers related to RLV-TD so far control surfaces on winged body don't play any role during ascent phase.
