Plex Security risks

General Discussions

Hi there

I have been looking into making my plex server available outside my network, I am running Plex alongside Open Media Vault 5 using portainer and I was wondering if by making Plex available outside my network if it also makes OMV also available outside my network. Basically does port forwarding plex allow for the rest of the system to be exploited or has plex got its own security to secure that port.

Any information about this would be greatly appreciated.

Is that still the same (underlying) question as back in April?

A port forward allows you (and others) to access a service running on a specific machine in your home network. It does not provide outside access to the entire network or the entire server… just that one service running on the defined internal port (32400: Plex).
Within Plex, the user gets to see what they’re authorized to see:

  • if a user has no Plex account, they’ll fail to login into Plex
  • if a user has a Plex account but you haven’t shared anything with them… they’ll see an empty Plex Web at best (but none of your content)

Things usually only get tricky if you messed things up elsewhere and e.g. publicly posted your Plex Token (maybe for the use by another app)

Hi Thanks for your response…

So would the port forward only make the internal port available outside the network as well as all of the media files etc. so any other webui’s on the system cannot be accessed externally.

It’s not opening up other applications nor does it open your media files — it’ll only allow access to your media through Plex.

Thanks for your help,
Does this basically mean that it only has access to plex and not the rest of the system, and plex is also secured with a user login system.

Yes, that’s correct.
