Please check with an old card like a Circle of Protection and with a more recent card : I suspect is an hardcoded bug.

Your assumption turned out to be correct. Neither CoP:Red nor Reverse Damage can be used to prevent damage dealt by a Banefire with x≥5.
I also tested it with cards that didn't come with the base game and it turned out that cards using/asking to target damage cards to determine which and how much damage to prevent can't prevent Banefire with x≥5 either. Thought Lash would be an example for such a card.
Cards that can be activated/cast before the spell/ability causing damage has been cast/activated can prevent that damage. Divine Deflection works like that.
