Any way to browse OSVDB?

As of today (April 5th, 2016) The project was shut down due to lack of contribution, and there is no plan for it to return.

As of today, a decision has been made to shut down the Open Sourced Vulnerability Database (OSVDB), and will not return. We are not looking for anyone to offer assistance at this point, and it will not be resurrected in its previous form.

This (CVE Reference Map for Source OSVDB) can be useful:
