Description Doran Moppert 2017-09-28 00:28:04 EDT

The content security policy (CSP) sandbox directive did not create a unique origin for the document, causing it to behave as if the allow-same-origin keyword were always specified. This could allow a Cross-Site Scripting (XSS) attack to be launched from unsafe content.
