Alertmanager status endpoint requires a new permission
The GET /api/alertmanager/grafana/api/v2/status endpoint previously required the legacy alert.notifications:read permission. It now requires a dedicated alert.notifications.system-status:read permission. This new permission is included in the fixed:alerting.notifications:writer role, which is granted to Admin users by default.
You are affected if
You use the GET /api/alertmanager/grafana/api/v2/status endpoint and rely on the alert.notifications:read permission to access it.
Migration
If you have custom roles that need access to this endpoint, add the alert.notifications.system-status:read action to those roles. Admin users are unaffected as they receive this permission automatically through the built-in alerting notifications writer role.
