CVE-2026-33377

A flaw was found in Grafana. A user with editor privileges can overwrite a dashboard not owned by them, leading to privilege escalation on that specific dashboard. This allows the editor to gain administrative control over the affected dashboard.

A privilege escalation flaw exists in Grafana, allowing an authenticated editor with write access to a dashboard to overwrite other dashboards not owned by them. This grants the editor administrative control over the targeted dashboard, potentially leading to unauthorized data manipulation or exposure within the Grafana environment.

Red Hat's default deployment does not grant edit access to normal users. Hence, this is rated moderate.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Audit dashboard-level permissions to ensure that write access is granted only to users who should be able to modify each specific dashboard. Revoke per-dashboard write permissions from Editor users who do not strictly require them.
