What it is about
Grafana ist eine Analyse- und Visualisierungssoftware. Ein entfernter, authentisierter oder anonymer Angreifer kann mehrere Schwachstellen in Grafana ausnutzen, um einen Denial of Service Angriff durchzuführen, Code auszuführen oder Informationen offenzulegen.
Under what conditions?
Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Denial of Service Angriff durchzuführen
- Code auszuführen oder Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- Red Hat Enterprise Linux
- Grafana Grafana <12.3.0
- Grafana Grafana <12.2.0
- SUSE Linux
- Oracle Linux
- RESF Rocky Linux
- Grafana Grafana <12.0.0
- Grafana Grafana <12.4.0
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Grafana Grafana 12.3.0
- Grafana Grafana 12.2.0
- Grafana Grafana 12.0.0

Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
