What is CVE-2015-4478?

This vulnerability in Mozilla Firefox allows remote attackers to bypass the Same Origin Policy. Specifically, it arises from insufficient requirements on JavaScript object properties when using ECMAScript 6, particularly via the reviver parameter of the JSON.parse method. This could lead to potential security breaches, as attacker-supplied JavaScript may be executed in privileged contexts, undermining user security and privacy.
