Their extremely enhanced cellular regeneration takes care of both problems (incineration and biochemical assault). It might leave them incapacitated for a few minutes while they heal, and they certainly would feel it, but it likely wouldn't kill them. They couldn't withstand being thrown into a star, but they could withstand the heat of a direct energy projectile. It would hurt, but they could do it.

Aetanii can withstand the vacuum of space for a short time, even without biocybernetic modification, and Seirōkishi can survive extended periods. Say, ten or fifteen minutes. That's enough time to escape through an emergency hatch, find a way to the nearest starship, and cut their way in with their lightsaber.
