      The more policies I look at in the wild, the more convinced I am that we need to wrap up CSP3, then start over with something more straightforward, like https://mikewest.github.io/artur-yes/ .

      Not asking for a free test, but I wonder what you think of the CSP on: https://portal.contact-associates.co.uk  It’s even stricter when you enable DNT on your browser :-)

      form action is likely to break something involving redirects, protocols are unnecessary, use a proxy solution for google analytics

      script-src on GA domains is still a bypass if you set 'unsafe-eval'.

          Integration with https://developers.google.com/tag-manager/devguide … which supports custom macros that get eval()ed after you include the attacker's container. Also: you do your own offensive research!!

          OT what's the likelihood of the internet moving towards data-* attributes over script tags that set data?
