Overview

tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.

Affected versions of this package are vulnerable to Open Redirect via the StaticFileHandler class, due to improper validation of the default_filename parameter in the initialize function. Exploiting this vulnerability is possible under specific configurations and might result in a redirect to an attacker-controlled site.

Note: This vulnerability is still under analysis and we are following up with the maintainers to confirm it.
