Grafana 5.3.1 has XSS via a link on the "Dashboard > All Panels > General" screen. NOTE: this issue exists because of an incomplete fix for CVE-2018-12099.
An information-disclosure flaw was found in Grafana through 6.7.3. The database directory /var/lib/grafana and database file /var/lib/grafana/grafana.db are world readable. This can result in exposure of sensitive information (e.g., cleartext or encrypted datasource passwords).
In Grafana 2.x through 6.x before 6.3.4, parts of the HTTP API allow unauthenticated use. This makes it possible to run a denial of service attack against the server running Grafana.
