What is CVE-2026-21722?

In Grafana, a vulnerability arises due to public dashboards with annotations enabled, where the annotation time range is not restricted to the locked time range of the dashboard. This flaw allows users to access the entire history of annotations displayed on the dashboard, potentially exposing sensitive information that should be limited to specific time frames. Importantly, no annotations that would not ordinarily be visible on the public dashboard are leaked.
