Drawing attention on this instance so Admins are aware and can address the propagating exploit.
EDIT: Found more info about the patch.
A more thorough recap of the issue.
GitHub PR fixing the bug: https://github.com/LemmyNet/lemmy-ui/pull/1897/files
If your instance has custom emojis defined, this is exploitable everywhere Markdown is available. It is NOT restricted to admins, but can be used to steal an admin’s JWT, which then lets the attacker get into that admin’s account which can then spread the exploit further by putting it somewhere where it’s rendered on every single page and then deface the site.
If your instance doesn’t have any custom emojis, you are safe, the exploit requires custom emojis to trigger the bad code branch.
Tbf, there are far more pressing reasons for distrusting Tankies… Instances getting hacked is for sure aggravating, but it isn’t the gulag-backed paranoid ultra-corrupt authoritarian hellhole they so admire and wish to expand globally.
I realize that you’re using ‘my lord’ as a bit of an exclamation here, but I initially read it as you addressing the commenter as your lord. it just made me imagine you with a heavily British accent, going full medieval peasant style to mock the guy. I found that quite humorous.
Spreading FUD over a group of people’s intent with their software that they personally use is an odd take, when kbin could very well have similar vulnerabilities in its codebase. Federation is good as part of limiting the attack vector one of many implementations and a subset of all servers hosting and routing media content. Kbin is just another set of federated content servers, with there being no guarantee of who develops the software being inherently more competent than those who develop Lemmy.
The Lemmy devs are ideological fans of communist China.
They’re likely to cooperate with them down the line and take actions that compromise their software, send data to others who are in their circle, and so on and so forth.
A lot of people say since Lemmy is open source you can trust it, but open source isn’t a protection against malicious code. Here you can see an example of just how easy it is to sneak something by. Even though this wasn’t a malicious example it still allowed admin accounts to be compromised
You seem to be coming up with conspiracy theories, don’t you?
And you don’t seem to know how (developing) software works, and that people aren’t infallible when it comes to avoiding bugs.
Popularity just also increases the attack surface to a project, all these bugs can absolutely also occur in kbin. Unless software is mathematically proven (which is practically impossible in this context), it’s always possible that there is a bug lurking around the corner.
I know you’re getting it from all angles right now, but
Do you have a source for their support of Communist China? I know they’re purported communist, but I didn’t notice any outright support of the Chinese form of communism.
Not trying to argue, but genuinely trying to stay informed
Lmao you very clearly have absolutely no idea what you’re talking about.
I dislike tankies myself, but this was absolutely not a backdoor.
I literally said this wasn’t in my comment. This is evidence of how easy it is to sneak in a back door.
This comment further underlines to me that you have absolutely no idea what the fuck you’re talking about.
You’re out of your element, Donny.
And this is why you don’t trust tankies. It’s very easy to compromise the software and put back doors into it.
This is hardly a back door. The lemmy devs just screwed up.
Use kbin instead.
Kbin had a fix for an SQL injection exploit the other week. Both probably still have security holes that haven’t yet been identified.
There are more eyes on the software as the userbase grows, and people are going to find more flaws. That’s just the way things go.
This is hardly a back door.
I literally said it wasn’t in my comment, it’s evidence of how easy it is to put one in down the line despite the fact this is open source software.
This comment is so idiotic that its least stupid explanation is that it’s a false flag by a tankie to make their critics look like idiots.
Its open source and a lot of people are looking at it. The odds it has a back door intentionally put there are slim to none. It would get noticed.
Don’t know, I don’t have enough information. Though my point were if it were intentional. I am going to hazard a guess by how they are scrambling to send out patches that it probably wasn’t intended by the creators.
The kind of developers that would put a back door in their software probably are also working on things with far more value potential than an open source forum where they could easily be caught. Perhaps like banks or weapons depots.
