I doubt your pup will be severely injured if anything she'll learn what not to do to the cats or end up severely injuring one of them

. I just got my first cat so I have no advice, but so far my one dog is afraid of the cat and my other just looks at her no lunging or barking.
I suggest teaching your pup some manners by keeping her leashed to you and keeping her away from the cats until you find the distance at which she can see them, but not react. Mark this behavior with a clicker and tons of treats working your way closer and closer until she no longer is barking and lunging. They may never like each other and this method will probably take a month or more, but being your pup is so young you should be able to teach her kitty manners if you commit to it
