+	  <p>On August 9 an internal security review identified a vulnerability
+	  in the Grafana which allows an escalation from Admin privileges
+	  to Server Admin when Auth proxy authentication is used.</p>
+	  <p><a href="https://grafana.com/docs/grafana/latest/setup-grafana/configure-security/configure-authentication/auth-proxy/#configure-auth-proxy-authentication">
+	  Auth proxy</a> allows to authenticate a user by only providing the username
+	  (or email) in a <code>X-WEBAUTH-USER</code> HTTP header: the trust assumption
+	  is that a front proxy will take care of authentication and that Grafana server
+	  is publicly reachable only with this front proxy.</p>
+	  <p><a href="https://grafana.com/docs/grafana/latest/developers/http_api/data_source/#data-source-proxy-calls">
+	  Datasource proxy</a> breaks this assumption:</p>
+	  <ul>
+	    <li>it is possible to configure a fake datasource pointing to a localhost
+	    Grafana install with a <code>X-WEBAUTH-USER</code> HTTP header containing
+	    admin username.</li>
+	    <li>This fake datasource can be called publicly via this proxying feature.</li>
+	  </ul>
+	  <p>The CVSS score for this vulnerability is 6.6 Moderate
+	  (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H).</p>
