I'd love to switch. I would do it right now, but the problem is that Jellyfin's security isn't better if you open it up to the internet. For example, I'd have to set up a VPN for my remote users for proper security, and most of my users are in other states, not technically inclined, and watch on their TVs. I'd have to at least support a raspberry pi for them, or some sort of site to site VPN, and if it goes down, I'll be expected to fix it. On top of that, if I do a simple raspberry pi based VPN, it would be made even more complicated since they'd want it to work with their smart TVs.

Again, I really want to switch. But Jellyfin needs to fix their security issues before I can. I'm also happy with the way Plex is reporting this, it's above the standard "your data is lost" notifications.

Edit: here's a link to the related GitHub issue I've been following: https://github.com/jellyfin/jellyfin/issues/5415

And @Saik0Shinigami@lemmy.saik0.com has a great thread explaining more: https://lemmy.today/comment/18923504

Jellyfin is great... As long as you're the only one who needs to access the server. I've switched to using Jellyfin myself, but I still run Plex for others to access.

I've found that I get a smoother playback experience on Jellyfin, but even outside of potential security issues, there are a still couple of features I miss from Plex.

One was automatic collections, but the plugin for this has since been updated, and the bug I was experiencing has been fixed. The one remaining feature that I'm missing is user ratings for media. On Plex I have automatic collections of movies that I've rated four and five stars, and it's quite useful.

My big complaint with Jellyfin is that their documentation showed a “fast forward” hotkey that convinced me to switch from Plex, and when I started it up it was a misnamed “jump forward five seconds” button instead.

It’s still better for my needs, but I remain angry.

Most of these require some form of random id to exploit, which leaves you either brute forcing ids or brute forcing a user account

[–] MaggiWuerze@feddit.org 1 points 4 hours ago* (last edited 3 hours ago) (1 children)

Again, its not random. It's not a UUID. Its an md5 hash of the filepath. Which is easily guessable since most people have a very similar if not identical folder structure, especially since a lot have it managed by the *arr suite. take that plus the publicly available release names for movies and you're done

[–] ChairmanMeow@programming.dev 2 points 4 hours ago (1 children)

Put your files in a randomly named root folder and it's fixed. Even still, isn't the worst they could do pirating your service?

[–] MaggiWuerze@feddit.org 0 points 3 hours ago* (last edited 3 hours ago) (2 children)

No, the worst is that a company like Sony or their lawyers can find my server and create a list of movies I offer and then sue me over it. I live in a country where lawyers make a living doing nothing but that.

Besides that, security by obscurity is the worst possible form and barely qualifies as security at all. It's also another place where the Jellyfin devs leave their users to their own devices when it comes to securing the server against malicious actors.

And none of this is clearly communicated by the project. The unauthenticated endpoints are not disclosed, the issues with the filepath is not disclosed. Jellyfin fans treat it as a drop in replacement for Plex, but people using it as such basically throw an unauthenticated server onto the open web

Besides that, security by obscurity is the worst possible form and barely qualifies as security at all.

In fact security by obscurity is not security at all. In this case it should be authenticated or to the very least to actually use a random string like a uuid. But, changing the root path does prevent it from exploiting. Not perfect but a temporary solution.

It's also another place where the Jellyfin devs leave their users to their own devices when it comes to securing the server against malicious actors.

Another place? What else? You mean setting up you own server? That is in fact your responsibility.

[–] exu@feditown.com 2 points 3 hours ago

I live in a country where making copies of movies and having them for private consumption isn't illegal.

I wouldn't blame the Jellyfin devs for this situation, they inherited a lot of bad code from Emby and are still cleaning it up.

[–] FreedomAdvocate@lemmy.net.au 1 points 7 hours ago (1 children)

If you hand wave those away then you can’t possibly have any issue with Plex.

[–] exu@feditown.com 1 points 5 hours ago

I don't have an issue with Plex. I don't use it

[–] AmbiguousProps@lemmy.today 3 points 16 hours ago (1 children)

I mean, that's fine, but it's still an issue and a risk that would cause me to want to use VPN for remote viewing. It doesn't seem like security is Jellyfin's priority at the moment, not that it's Plex's either, but it's not to a place where it's worth it to switch from a security standpoint, personally.

[–] MaggiWuerze@feddit.org 3 points 4 hours ago (1 children)

Plex has a whole team dedicated to security. It's obviously not perfect and it is a larger attack surface than Jellyfin, but I'll take that any day over devs who treat security as an afterthought

[–] Orygin@sh.itjust.works 0 points 3 hours ago (1 children)

You mean the security team that got pwned here?

[–] MaggiWuerze@feddit.org 0 points 2 hours ago

Still better to have a team to react to this incident than just have them shrug and ignore it for 5 years

[–] atomicbocks@sh.itjust.works 3 points 18 hours ago

This is the same reason I haven’t switched. My parents use it to watch the local OTA channels and I have zero intention of supporting a site to site VPN on their home network and multiple mobile devices.

[–] TrickDacy@lemmy.world 2 points 20 hours ago

Thank you for that issues link. I keep trying jellyfin every now and then and I run into issues with general bugginess so I haven't been able to switch. Seeing that it's kinda full of security holes makes me even more reticent.
