Privilege escalation
Summary
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
Impact
Unauthenticated users can query arbitrary endpoints with malicious intent.
Impacted versions
All installations for Grafana versions >=9.2.x.
Solutions and mitigations
To fully address CVE-2022-39328, please upgrade your Grafana instances.
Appropriate patches have been applied to Grafana Cloud.
