When an iframe has a sandbox attribute and its content is specified using srcdoc, that content does not inherit the containing pages Content Security Policy (CSP) as it should unless the sandbox attribute included allow-same-origin. This vulnerability affects Firefox < 55.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
