Overview

clearance is an authentication app for rails.

Affected versions of this package are vulnerable to Open Redirect. The vulnerability can be possible when users are able to set the value of session[:return_to]. If the value used for return_to contains multiple leading slashes (/////example.com) the user ends up being redirected to the external domain that comes after the slashes (http://example.com).
