What is CVE-2026-13720?

A vulnerability in Grafana allows an Editor role to provision file-specific metadata without proper authorization checks through the dashboard API. This can result in dashboards being classified as file-provisioned, which subsequently prevents administrators from updating or deleting these dashboards. The issue is confined to the organizational scope, ensuring that no user data is exposed externally.

Affected Version(s)

Grafana Enterprise 12.0.0 <= 12.0.10

Grafana Enterprise 12.1.0 <= 12.1.10

Grafana Enterprise 12.2.0 <= 12.2.11
