Here's a Wikipedia summary for those who don't remember the incident:

The Fappening was alluded to by tweet asking whether Weinstein's phone could be source of those leaked photos.

Did "The Fappening" originate from Harvey Weinstein's iPhone/iCloud account? This post is from 2016... @Cernovich

I'm not familiar with this Twitter account, but a screengrab is posted that says:

1. Apple maintained there was no hack to iCloud
2. That the photos were the result of an "MAJOR HOLLYWOOD FIGURE" being broken into.
3. That the photos were taken by this self-same MAJOR HOLLYWOOD FIGURE during the audition process

It's a theory, but one that could be true given what we know.

And before I forget here's the denial from Apple that its servers were hacked:
