Details

This affects all versions of package Flask-Security. When using the getpostlogoutredirect and getpostloginredirect 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 'autocorrectlocationheader=False. Note: Flask-Security is not maintained anymore.
