Hackers could steal local files from a Microsoft Edge user thanks to a security vulnerability in the older versions of the browser. Security researcher Ziyahan Albeniz revealed that the flaw is with the Same Origin Policy (SOP) that prevent attackers from accessing local files.

“The Same Origin Policy (SOP) would prevent https://attacker.com from reading file://C:/your/stuff.txt, for example,” Albeniz wrote. “The reason is that they have different origins.”
