Technically, all notebook servers are affected, but only established notebook server hosts can logically create these maliciously constructed connections. A connection to your notebook server will seem stable, but it will inevitably be diverted to a spoofed server on the public Internet. The problem is corrected in version 6.1.5.

What kind of vulnerability is it? Who is impacted?

Open redirect vulnerability – a maliciously crafted link to a notebook server could redirect the browser to a different website.

All notebook servers are technically affected, however, these maliciously crafted links can only be reasonably made for known notebook server hosts. A link to your notebook server may appear safe, but ultimately redirect to a spoofed server on the public internet.

Has the problem been patched? What versions should users upgrade to?

Patched in notebook 6.1.5
