* Allow content source to fallback to default-src Remove defaults for script-src, style-src, connect-src, and img-src so that they can fallback to default-src. The default for default-src has been changed from 'none' to 'self'. This seems to be a safe default especially as browsers implement prefetch-src. If stricter policies are needed they can be specified when loading this middleware. * Add support for webrtc-src, navigate-to, and prefetch-src directives |
