CVE-2026-21722

A flaw was found in Grafana. Public dashboards with annotations enabled fail to limit their annotation time range to the locked time range of the public dashboard. This flaw allows an attacker to retrieve the entire history of annotations visible on that dashboard, including those outside the locked time range.

This issue only exposes annotations that would otherwise be visible on the public dashboard if the time range were different, it does not leak annotations from private dashboards or data that is restricted by other permission models. Due to this reason, this vulnerability has been rated with a moderate severity.
