The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions: action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.

A vulnerability has been discovered in Grafana OSS where an authorization bypass in the provisioning contact points API allows users with Editor role to modify protected webhook URLs without the required alert.notifications.receivers.protected:write permission.
