The Alertmanager in Grafana Enterprise Metrics before 1.2.1 and Metrics Enterprise 1.2.1 has a local file disclosure vulnerability when experimental.alertmanager.enable-api is used.

The alertmanager templates can be used as an attack vector to send any file content because the alertmanager can load any text file specified in the templates list.
