Incorrect Access Control Vulnerability (CVE-2019-15043)

We received a security report to security@grafana.com on August 12, 2019, about a vulnerability in Grafana involving incorrect access to the HTTP API. It was later identified as affecting Grafana versions from 2.0.0 to 6.3.3. CVE-2019-15043 has been reserved for this vulnerability.

This vulnerability allows a user/client to access parts of the Grafana HTTP API without being authenticated. This makes it possible to run a denial of service attack against the server running Grafana.

Affected Versions

Grafana releases 2.0.0 through 6.3.3
