Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I’ll be sticking to Plex until it is reasonably safe to expose JF.

Have you even read the issues and understood them?

Yes, those should be fixed, but unless you are worried about someone hijacking a video stream when you use a generic media path, there is not that much to worry about.

All (raw) image endpoints in ImageByNameController, ImageController & RemoteImageController are unauthenticated

  • This allows probing on whether a specific image exists on the server by guessing item id's (which can be done without too much trouble, as item ids are based on filepath and filename information) and then checking on what content (movies, series etc) exist on a given server, without having an account.

As I said, when you know the exact path of a media item on the server then you can check if the item exists.

If you choose a none standard filepath its not an issue.

Should that be fixed yes.

Whats the scenario? A law firm could brute force check all media items on open jellyfin servers? Highly illegal to exploit something like this in a lot of jurisdiction. And would also not proof the existence of the media on the server, just a file named like it.

Mitigation? Just add another random letter in the docker-compose mount path.

You shouldn't be exposing any self-hosted service to the public Internet, unless you're willing to also monitor for potential breaches.

You should really not be exposing jellyfin OR plex to the open Internet. It's just asking for trouble.

that's literally the feature of Plex....
