Details

https://groups.google.com/a/chromium.org/forum/#!msg/isolation-policy/zueJF9ad20g/XYL_YXHgAwAJ https://github.com/whatwg/html/issues/3740 COWP is a mechanism to break DOM access across windows. Components of COWP have been proposed, however the final specification is not finalized. Proposals ahve included: a) Severing window.open: Making window.opener and the result of window.open appear as if the referenced window was closed (.closed is true) b) Severing iframes: Making an iframe's window.parent, and the embedding reference iframe.contentWindow, appear as if the referenced window was closed c) Preventing navigation of referenced windows (window.parent, window.open, iframe.src) d) Blocking (or selectively allowing) postMessage e) Limiting or restricting the use of document.domain f) Requiring setting CORP and/or X-Frame-Options to limit embedding/framing
