A number of Lemmy instances have been hacked overnight. Some may remain
inaccessible until they have been secured and restarted. As a safety precaution
logged-on sessions on many servers have been cancelled and you are required to
logon again. Unfortunately, the only way I could find to do this in L...
Drawing attention on this instance so Admins are aware and can address the propagating exploit.
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.
yeah, kind of insane the grudge people hold about it, people like that user spread all these spooky posts about how the devs are communists coming to kill you or something and that's why you should use kbin (I'm only slightly exaggerating, the way these people post about it makes it sound like the devs are directly involved with like human rights abuses or something lol)
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.
