- Summary
- Open redirect in Flask-Unchained
- Details
-
This affects the package Flask-Unchained before 0.9.0. When using the the validateredirecturl function, 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 'autocorrectlocation_header=False.
