What exactly happened on the superconductor market today?

@TamarSpoerri Embeds were apparently implemented through un-sandboxed iframes, and someone embedded a page (in a comment) that caused a redirect in the parent.

(I think not intentionally on the commenter's part. They were linking to a video, and the website hosting it probably has frame-breaker stuff set up in general.)

I should probably define "exploit" for the purpose of this market...

@jskf I strongly suspect that bilibili's frame-breaker is on the 404, not on all videos, and it was only when the video was taken down that the redirect started happening. otherwise, the commenter would've been redirected when the embed-preview shows up while they were editing the comment.

(haven't actually checked tho)
