CVE-2026-28378
Description
A flaw in Grafana's public dashboard deletion endpoint lacks organization isolation, allowing an Organization Administrator to delete public dashboards in other organizations using the target dashboard's ID.
Statement
This Low impact flaw in Grafana allows an authenticated Organization Administrator to delete public dashboards belonging to other organizations. This is due to insufficient isolation enforcement in the public dashboard deletion endpoint, potentially affecting the availability of dashboards in multi-organizational Grafana deployments.
Mitigation
Since this vulnerability only affects the Public Dashboards feature, environments that do not utilize public dashboards can completely neutralize the risk by disabling the feature. This removes the vulnerable endpoint from the attack surface entirely.
