CVE-2026-33377
Description
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.
Statement
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.
Mitigation
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
