Security researcher Collin Jackson reported a violation of the HTML5 specifications for document.domain behavior. Specified behavior requires pages to only have access to windows in a new document.domain but the observed violation allowed pages to retain access to windows from the page’s initial origin in addition to the new document.domain. This could potentially lead to cross-site scripting (XSS) attacks.
