CVE-2019-19916
Midori Browser Multipart Content CSP Bypass Vulnerability
Description
In Midori Browser 0.5.11 (on Windows 10), 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 result in script running where CSP should have blocked it, allowing for cross-site scripting (XSS) and other attacks when the product renders the content as HTML. Remediating this would also need to consider the polyglot case, e.g., a file that is a valid GIF image and also valid JavaScript.
