Repair interior side of stucco siding

I'm in the process of redoing a bathroom and after taking down the drywall I found some rot. I am going to create a splint for the 2x4, but I am not sure what to do with the back of the stucco that is exposed due to the rotted wood. I believe the water came from the inside and probably before the last time the bathroom was redone prior to me owning the house.
I'm not really finding anything about this on the internet so any help is greatly appreciated!

You really can not fix stucco from the inside. Trying to remove any of the framing will likely damage the stucco. If your framing is rotted, your best bet would be to leave it and sister new stuff next to the old.

Sorry I'm not really following what you are saying. I was going to splinter a new 2x4 in next to the 2x4 that has rotted. Don't I need to water proof the back of the exposed (whiteish) stucco? I could add more of the paper but I was thinking I should get some liquid sealant like the stuff that is used on shower floors?

Like I said, you can't really do it properly from the inside. If you put felt paper up, the bottom of that new felt paper needs to shed water over the top of the existing paper, which is stuck to the stucco. If it's just laying on the inside, that's not really doing much of anything, other than covering it. If water gets behind the stucco it's still going to leak.

Sure you could put something on it but it's not going to be right. Maybe look into flex seal tape and flex seal spray. That's the best you can do.
