Seems like you wouldn't be able to actually use this vulnerability without a valid nonce, so I don't see how you would trigger this unless you have some sort of malicious plugin also installed on the site . . ?

Some sites have plugins that allow users to create accounts with minimal permissions.

An attacker could create such an account, then abuse a legitimate nonce to delete files.

Not sure why someone would do this, but even without a plugin you can go to General Settings and set New User Default Role to Author. This would give any new accounts the ability to exploit this.

Yeah, I didn't notice the video in the article with the proof-of-concept demonstrates this. Thanks.
