Plex Media Server Compromised?

Server Version#: 1.41.3.9314 (latest) (Windows 10)

Hi so I’m running Plex and I got this notification from Bitdefender:

“The page <url removed for safety reasons (it’s in the pic)> has been detected with suspicious activity. It is not recommended to continue browsing this website. Accessed by: plex media server.exe”

Has anyone seen this before? I’m not sure what to make of it because everything is up-to-date (Plex, Windows) and I just find it hard to believe that it’d be a 0day

It doesn’t seem to be a false positive either? It’s some Chinese website

Edit: I’m also doing a system scan and I have it disconnected from the internet for the time being

Do you remember what exactly you did/looked at, that lead to this warning?
The address is not something that occurs in Plex as such. So my suspicion would be that it was inserted into metadata, like an artist biography or similar.

Have you experimented with Plex plug-ins?
Is it possible that it is caused by some long-forgotten plugin that was installed and never removed?
Better remove them all: https://support.plex.tv/articles/201187656-how-do-i-manually-install-a-plugin/
(If you remove one of the default plug-ins, you might have to start the installer for Plex Media Server again to restore them, but that’s no biggie.)

I wasn’t doing anything, it was just sitting there lol

I also don’t have any plugins installed and never have

I think it being in metadata somewhere is the most reasonable explanation but I’m not sure, I couldn’t find anything about it in my logs

Were you able to capture a copy of your logs shortly after this happened? perhaps we can narrow down what was happening in plex.

Not sure if it is related but my Malwarebytes is regularly detecting ‘website blocked due to compromised’ and this is associated with Plex Media server.exe.
