Leaving aside for a moment the technical issues involved in actually constructing a wormhole … once a wormhole is constructed, traversing it doesn’t involve violating any physical laws. You’re simply moving along a trajectory through space.
All that’s different from normal motion, is that the space you’re moving through, happens to couple distant points that would normally take you far longer to travel between, and the curvature of the space you’re moving through makes up for the discrepancy.
The question that’s far more difficult to answer, is whether or not the resulting topology is physically realisable.
