Thank you for posting this. I tend to get a lot of my opensource project info from Lemmy so people who take the time to post it are awesome.
Just updated my home instance. Can confirm that 10.11.7 is available in the Debian repos and the update went perfect. I got a new kernel in the same update : D
Just updated, thanks for the info <3
I forgot that it’s April first, and was wondering what catasthropic event had happend in order that it had to be stated in the title that its not a joke
Don’t expose jellyfin to the internet is a golden rule.
That’s never made sense to me; why build an authn frontend instead of just clicking your user if the security is just an illusion anyways. “Use a VPN” is fine for a mainframe, but an active project in 2026 should aspire to be better.
Edit: or make note of that on their several pages with reverse proxy configuration.
Examples dating back over six years https://github.com/jellyfin/jellyfin/issues/5415
I mean I’m sure they’d like to just ship safe code in the first place. But if that’s not their expertise and they demonstrate that repeatedly, we gotta take steps ourselves. Secure is obviously best, but I’d rather have insecure Jellyfin behind a VPN than no Jellyfin at all.
It’s not this or that. Security comes in layers. So while I would assume that the Jellyfin developers do their best to secure their application, I acknowledge the fact that bugs do exist and that Jellyfin is developed in and for hobbyist contexts, and thus not scrutinised and pentested for vulnerabilities in the way software meant for professional environments would be. Therefore I’ll add an extra layer of security by putting it behind a VPN that only whitelisted clients can access. If a vulnerability is detected, I can be sure it hasn’t already been exploited to compromise my server because we’re all “among friends” there.
Utilize authelia perhaps?
Doesn’t work with TVs
Kinda defeats the purpose of a media server built to be used by multiple people
No need to expose jellyfin to the internet if you selectively allow peers on your lan via wireguard.
This attitude is why Plex remains popular.
I’d rather just not use it at that point
Fair, you do you, I get a lot of value out of it instead.
The difference is that my friends get a lot of value out of my server, as they don’t need to use any technology they’re unfamiliar with.
Use a VPN, it’s not ideal but it’s secure.
Somehow difficult to install on a TV though.
That’s why you do it at your router or gateway and then set a route for the Jellyfin server through the VPN adapter. That way any device on your network will flow through the tunnel to the Jellyfin server including TVs
Which again implies that you have a router that allows you to do so. It’s not always the case. For tech enthusiast people that’s the case. But not for everyone.
I tried to do the same thing at first, but it was a pain, there were tons of issues.
Don’t reverse proxies like pangolin just do the job? Does it have to be VPN in this particular concept? VPN isn’t like immune to vulnerabilities.
Reverse proxy doesn’t really get you much security. If there is an application level issue a reverse proxy will not help
I see thanks. I’ll think about it more.
Reverse proxy will let anyone connect to it. VPN, you can create keys/logins for your intended users only. Having said that, from what I could see, nothing in the security fixes were to do with authentication. I think (just from a cursory look), they could only be exploited, if at all from an authenticated user session.
But personally, something like jellyfin where the number of people I want to be able to access it is very limited, stays behind a VPN. Better to limit your potential attack surface as much as you can.
Pangolin is based off of Traefik if I’m not mistaken, should be able to use Traefiks IPAllowlist middleware to blacklist all IP addresses and only whitelisting the known few, that way you can expose your application to the internet knowing you have that restriction in place for those who connect to your service.
Yahnlets see a roku use a VPN.
Y’all are assuming the security issue is something exploitable without authentication or has something to do with auth.
But it it could be a supply chain issue which a VPN won’t protect you from.
The thing is, if you have non-technical users, you have to set up the VPN connection on the client site yourself, maybe on multiple machines and more than once, if they decide to upgrade or even just reset their devices.
The problem here - it’s not me who requires access to my library, if someone isn’t willing or able to do it, I’m sorry but that’s just how it is. People should stop infantilize non-technical people, absolute majority of them is capable of navigating our world without much problems and I’m willing to help them if help is asked.
If my 60 y.o. mother with close to zero technical skills can do it with limited help (due to distance and other constraints) I’m pretty sure that majority of people with sound mind can.
Or you can not be arrogant towards your friends and family who have probably helped you on lots of occasions and will probably keep being there for you in the future.
Idk man, unconditional sharing feels pretty good, tbh. Making them jump through hoops isn’t really my jam. To me this kinda all plays into making a stronger bond with people that are close to me, so maybe we have different reasons for why we are sharing our stuff.Inb4 “we are not the same” meme
I’m not arrogant, just don’t assume that people are dumb and inept. If they can’t or don’t want to give a bit of time to setup it, well how can someone be forced to use free service that causes momentarily inconvenience once to use. 😔
This. And for everyone you just can’t figure it out on their own, there’s RustDesk for remote assistance. It, too, can be self-hosted.
So use a reverse proxy with authentiacation before access to Jellyfin is allowed. I use Caddy forward_auth with Authelia for this. Unless you also want to use the apps without VPN, this works great.
Does that work for the Android and Android TV apps?
No. As I said, apps don’t work. I cobbled together an API key service that let’s you have an API key (password) in the server URL in Rust for myself. This works with Apps, but it is a bit too messy and single purpose for me to open source it right now. Maybe one day.
Got instructions or a site to point to on setting something like that up?
Honestly, I may have to write one at some point. I just used the documentation of those two tools to set it up.
Yeah, i have my 30 docker containers behind Headscale (Tailscale).
NetBird is coming for you
I have been planning to check out Netbird for couple of days. Is it a good alternative for headscale and pangolin?
So don’t use it outside your house? Pass
Nothing stops you from using it outside of your house.
I just love it when people post one sentence rebuttals without actually including any usable information what they are talking about.
Tailscale is a super easy vpn that gives you access to your home network from anywhere. And it’s free.
The solution is mentioned already - use vpn, it will solve 90% of the problems that you can encounter. Also you can serve multiple other services this way without exposing them.
It kind of does. Whatever and yes I’m aware of the list people keep posting and I’ve looked at it.
The update rolled out perfectly for my Kubernetes setup (using the Docker image). 👍
Pretty flawless update from the apt repo on my end.
Server version 10.11.7There is a good reason I only have Jellyfin and other services accessible via valid Client Certificate.
Does it work with android and TV apps?
I tried long ago and failed.
No, we only use Jellyfin via browser. Unfortunately even with imported Client Cert, Android apps won’t work.
Edit: Client Certs need to be implemented per App. There is a feature request from 2022 https://features.jellyfin.org/posts/1461/capability-to-specify-client-certificate-for-android-client
Also interested how this works for mobile apps. I self host a number of services through caddy as my reverse proxy but each application is just dependent on it’s own authentication. If I exposed all my services to the internet, that’s a huge attack vector. If anyone else has some ideas I’d be happy to listen.
Wonder if it’s the Axios one. Sounds like it isn’t from their description though hmm
Axios is a Javascript library and Jellyfin is written in C#.
True, but there is a web frontend. Possible it could be using npm and axios somewhere in there.
I still doubt it. But it could happen.
The web server is in C#. It’s open source lol, I’m looking at the code and there’s no JavaScript.
Look better https://github.com/jellyfin/jellyfin-web
That’s awkward. I didn’t know that was in a separate repo.

I don’t think so, the previous release 10.11.6 is a few months old and the axios supply chain attack happened yesterday.
So lets hope this 10.11.7 is not subject to the axios one. :)
Diff agrees, not likely. Might be permisson related, elevation of privileges.
From a cursory look at just the security commits. Looks like the following:
- GHSA-j2hf-x4q5-47j3: Checks if a media shortcut is empty, and checks if it is remote and stores the remote protocol if so. Also prevent strm files (these are meant to contain links to a stream) from referencing local files. Indeed this might have been used to reference files jellyfin couldn’t usually see?
- GHSA-8fw7-f233-ffr8: Seems to be similar, except for M3U file link validation and limiting allowed protocols. It also changes the default permissions for live TV management to false.
- GHSA-v2jv-54xj-h76w: When creating a structure there should be a limit of 200 characters for a string which was not enforced.
- GHSA-jh22-fw8w-2v9x: Not really completely sure here. They change regex to regexstr in a lot of places and it looks like some extra validation around choosing transcoding settings.
I’m not really sure how serious any of these are, or how they could be exploited however. Well aside from the local file in stream files one.

Yeah, the key seems to be in the comments from one of the changes: https://github.com/jellyfin/jellyfin/commit/0581cd661021752e5063e338c718f211c8929310#diff-bcc2125e56d5738b4778802ac650ca47719845aeee582f3b5c9b46af82ea9979R1176-R1180
It seems there was the potential risk that insufficient validation could allow reading arbitrary server files, which indeed poses a security risk.
However, my understanding is that this could be exploited only by authenticated users with permission to add new media. Not like that’s a risk to ignore, but it’s not like it could be exploited by anyone on the Internet.

I wonder if that’s the reason for setting the default live TV management permission to false. Since that permission might well the the route to adding your own malicious m3u link for that second change.
Im on fedora and I have installed through dnf, no updates with the dnf update… should I wait?
I depends a bit on your threat model. If you have Jellyfin exposed to the internet I would shut it down immediately. If you are running locally and rely on it, let it run maybe? If behind a tailnet or some other VPN, I would deactivate it as well. If it is an Axios like vulnerability it may be possible your secrets are in danger, dependent on how well they are secured. Not a security expert, but I would handle this a little more conservative…
No need to shut it down if it’s not exposed to the internet. Tailnet/VPN is fine.
If it’s a supply chain compromise shutting it down wouldn’t matter. The damage is already done.
It’s on my home, which is not 24/7 open. Will see check later.
In the raspian repos, just updated, thanks.
also in the docker repository.

If only 10.11 were usable for me at all.
What’s the issue?
In addition to the other comment, it currently has some pretty rough performance issues with big libraries.
There was a regression that caused Jellyfin to be a LOT more restrictive regarding the structured filesystem format. But this could be something else
Edit: Maintainers told me they were gonna fix it
It’s probably database performance related. There’s a massive PR undergoing round after round of reviews that, when merged, will be a change to 10.12 and will resolve all of the new database performance issues experienced in certain edge cases (book libraries, large music libraries, large collections, etc)
samba vlc solved… you are welcome
I know you’re gatekeeping from Turd Mountain, but just for completeness, the reason I use Jellyfin besides the “pretty for my wife” reason is that it keeps track of her progress between clients. She sometimes watches things on her laptop, sometimes her phone, sometimes her tablet, and sometimes the TV, and no matter which one she uses it’ll remember which episode of her show is the next episode. It also highlights when a new episode of something has been added and cues her to watch the new episode that just came out.
But yeah, if I was alone and only had a pile of anime I’d already seen before, which I only watched from my Linux devices, Samba and VLC would do me fine 😛
Nope? how about fancy stuff GUI and plot?
IMDB on your phone I guess…Am I having a stroke?
At the time off writing you made a few more comments, so either “no” or “yes but your life is Lemmy”.
