Hi everyone.
Lemmy had an XSS vulnerability and we were one of the instances attacked through this vulnerability. We had our homepage replaced by a youtube video.
The lemmy devs were quick to create a PR for this issue and we have patched our instance to fix it,
Also while I do not believe any login tokens were compromised, we have taken the additional measure of rotating our secret key, so everyone will have to login to the site again as your existing credentials will no longer be valid.
If login fails to work properly, you may have to clear your cookies for the site... it seems to get confused about whether you're logged in or not.
Sorry that this happened, if you have any questions please contact @[email protected] or myself.
It seems like it is an identified issue with token invalidation in lemmy and they will be fixing (or have already fixed?) it in a future upgrade.
I'll keep an eye out for it and try to get it in as soon as possible. In the meantime, clearing site cookies while tricky is the only real option.
Thank you very much 👍🏻
