Swedish fintech payments unicorn Klarna shows you other users' account data

Comments moved to https://news.ycombinator.com/item?id=27301219, which was posted earlier; also, submissions to HN need to be in English. We have deep respect for other languages, but HN is an English-language site. It's important that the community be able to read an article. When people can't read an article they react purely to the title, which leads to shallower discussion. (Admittedly the other thread is merely a tweet, which is arguably not a whole lot better, but that's a separate issue.)
