This affects all versions of package Flask-Security. When using the
get_post_logout_redirect and get_post_login_redirect functions, it is
possible to bypass URL validation and redirect a user to an arbitrary URL
by providing multiple back slashes such as \\evil.com/path. This
vulnerability is only exploitable if an alternative WSGI server other than
Werkzeug is used, or the default behaviour of Werkzeug is modified using
'autocorrect_location_header=False. Note: Flask-Security is not
maintained anymore.
