Bug: I'm able to login as Plex user without PIN code

I was able to gain access to my full Plex library without entering my PIN code for my Plex user.

I have only 1 user. This user is protected with a pin code.
It’s a mere coincidence that I discovered this bug. I can reproduce it easily enough.

Open Plex HTPC for Mac (version 1.53.0.4063-cdc1f574)
The login screen automatically appears. From here you normally should select the user (in my case there’s only one) and enter the PIN code to gain access to the library.
However… This time I accidentally opened the Plex app. I didn’t want to launch it. So I was hitting the ESC and the Backspace key several times with the hope to get the exit-screen.
Instead after several key hits I was suddenly logged in to my user. Without entering the PIN! And yes, I have full access to my library.

As I said, I can reproduce this multiple times.

In attachment I include the logs from ‘Console’. You can see my key hits in the login screen at time stamp 00:50:52.

Plex server is version 1.32.8.7639 running on Synology.

Do you have any entries in Settings → Network → List of IP addresses and networks that are allowed without auth?

No, this field is empty.
