Grafana Labs reports:

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.

Auth proxy allows to authenticate a user by only providing the username (or email) in a X-WEBAUTH-USER 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.

Datasource proxy breaks this assumption:

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).
