CVE-2018-0771

This vulnerability describes a Same-Origin Policy (SOP) bypass in Microsoft Edge. The SOP is designed to prevent content from one origin (defined by port, protocol, and host) from accessing content within another origin. Bypassing this policy can allow content to be manipulated or transmitted between origins. For more details on the Same-Origin Policy, Mozilla has published detailed documentation.

Microsoft has rated this as a 2 on the Exploitability Index (Exploitation Less Likely).
