Description Huzaifa S. Sidhpurwala 2015-11-03 01:01:37 EST

Security researcher Frans RosÃ©n reported that URLs with certain escaped characters in hostnames are parsed incorrectly. This leads to parsing being abandoned when an effected escaped character is encountered followed by a navigation to the previously parsed version of the URL. When combined with a site allowing for navigation redirection that allows for escaped characters, this could lead to potential extraction of site specific tokens.
