Grafana Labs reports:

Internal security audit identified a race condition in the Grafana codebase, which allowed an unauthenticated user to query an arbitrary endpoint in Grafana. A race condition in the HTTP context creation could make a HTTP request being assigned the authentication/authorization middlewares of another call. Under heavy load it is possible that a call protected by a privileged middleware receives instead the middleware of a public query. As a result, an unauthenticated user can successfully query protected endpoints.

The CVSS score for this vulnerability is 9.8 Critical
