Description Doran Moppert 2018-05-09 07:13:29 UTC

Content Security Policy (CSP) is not applied correctly to all parts of multipart content sent with the `multipart/x-mixed-replace` MIME type. This could allow for script to run where CSP should block it, allowing for cross-site scripting (XSS) and other attacks.
