I found this secret box jump on ascent when playing around in a custom. I assume this is because of the small bump that is in the carpet that covers the wall of the box. I noticed the bump and tried this out because of a similar jump on breeze where there is a bump in the wall and by doing the same movement you are able to jump higher than what you should be able to.
