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. This
vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird <
52.4.
