I just found a security breach that can leak thousands of emails on a website!!
Today, I snooped around on a website I won’t mention the name of for privacy reasons, and they assign your account an user ID when you register.
Well, with a very simple trick in the console I managed to get everyone else’s email and account info (for example checking if they have a paid plan or not) by just lowering the user id, with no rate-limit on the endpoint!
So a bad actor could send targetted phishing emails to people by telling them there is a problem with their payment!
It’s funny because on their homepage, they state they use “Military grade encryption” (whatever that means!), and their privacy policy says “We encrypt the transmission of that information” (does that just mean they do it over https?)
So, moral of the story, don’t trust companies with your personal info!
I contacted the site, we’ll see if they fix it.
Email is always a traceable identification if you don’t use an mail with alias features or front-end…
