Oh no, that looks like the beginning of floppy mimosas.
IME, you need to address it or it will get worse, and its an issue of too little/low intensity light. You can add some soil around the base to prop it some, but you need to get it under stronger or longer daily light, ideally acclimate it outside. Also, add a fan if you keep it inside as a little wind gives it some exercise.
I had 3 like that that I let progress, and they are no more. 2 of them were staked with supports to see if the trunk would strengthen with some temporary help, and when the supports were removed they were way worse than the one left without stakes. It was like they figured they didn't have to worry about holding themselves upright anymore.
