firefox is vulnerable to cross-site scripting (XSS). When an inner window is reused, it does not consider the use of document.domain
for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain
, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those that did not use document.domain
to relax their origin security.
