CORS: the ultimate guide

Imagine visiting a website showing innocent kitten pictures. But behind all those cute feline creatures hides this website’s superpower. As soon as someone visits this website, the owner of the website gets access to all the visitor’s online presence. He gets access to your banking information, your social media posts and messages, your emails, your online purchases, etc. Imagine the damage this would do to your reputation and your finances. He could leak your messages and deplete your bank account. But thankfully, this scenario will not happen. And it’s all thanks to SOP and CORS.
