| Doc Text: |
A flaw was found in Grafana. A remote attacker with very low privileges, or even anonymous access if enabled, can exploit the alertmanager templates test endpoint by mass-executing templates. This can lead to an Out-Of-Memory (OOM) error, causing the Grafana service to crash and resulting in a Denial of Service (DoS).
