+	  <p>Login pages tend to take a parameter for redirecting back to a page
+	    after successful login, e.g. /login?next=/notebooks/mynotebook.ipynb, so
+	    that you aren't disrupted too much if you try to visit a page, but have
+	    to authenticate first. An Open Redirect Vulnerability is when a
+	    malicious person crafts a link pointing to the login page of a trusted
+	    site, but setting the "redirect after successful login" parameter to
+	    send the user to their own site, instead of a page on the authenticated
+	    site (the notebook or JupyterHub server), e.g.
+	    /login?next=http://badwebsite.biz. This doesn't necessarily compromise
+	    anything immediately, but it enables phishing if users don't notice
+	    that the domain has changed, e.g. by showing a fake "re-enter your
+	    password" page. Servers generally have to validate the redirect URL to
+	    avoid this. Both JupyterHub and Notebook already do this, but the
+	    validation didn't take into account all possible ways to redirect to
+	    other sites, so some malicious URLs could still be crafted to redirect
+	    away from the server (the above example does not work in any recent
+	    version of either package). Only certain browsers (Chrome and Firefox,
+	    not Safari) could be redirected from the JupyterHub login page, but all
+	    browsers could be redirected away from a standalone notebook server.</p>
