Description Huzaifa S. Sidhpurwala 2015-11-03 05:49:47 UTC
Security researcher Michał Bentkowski reported that adding white-space characters to hostnames that are IP addresses can bypass same-origin policy. This flaw was caused by trailing whitespaces being evaluated differently when parsing IP addresses instead of alphanumeric hostnames. This could lead to a cross-site script (XSS) attack.
