Could NATO Accept a new member who is at war?

There are many reasons why NATO would not want to accept Ukraine as a new member state right now. The most prominent reason being the perception that this would increase the chance of a nuclear conflict. Now this may of course be true, but we may also be wrong here.

If, let's say, NATO were to consider accepting Ukraine, would it be possible at all? Are there limitations in the NATO charter that prohibit Ukraine from entering simply because they are presently in a state of war? Are there other major reasons why this is not an option?
