It depends whether the fleeing is considered controlled, as in the person fleeing still has some sense of self-preservation, or whether the fleeing is an uncontrolled mindless panic, in which case the person fleeing can easily run off a cliff, into lava, or on/in to whatever other hazards may lie in the path.Why wouldn’t you run into lava while fleeing something?
For me, spells like Command would produce the former while fright spells like Spook or something like the flee-in-terror effect of a Ghost would produce the latter.
Running away in itself isn't directly harmful. Running into a hazard while running away is IMO indirect harm.The spell also prohibits actions that are directly harmful to the target.
