Summary
An authorization bypass vulnerability in Grafana through 13.2.0 allows an Editor-role user to delete protected contact points (receivers) without the required alert.notifications.receivers.protected:write permission.
An authorization bypass in Grafana allows Editor-role users to delete protected contact points because a previous security patch for updating them missed the deletion process. This could disrupt alert notifications in Red Hat deployments where Grafana is configured with alert managers and Editor-role users have access to manage alert configurations.
Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N). Weakness: CWE-284.
Affected Red Hat products: Multicluster Global Hub; Red Hat Advanced Cluster Management for Kubernetes 2; Red Hat Ceph Storage 5; Red Hat Ceph Storage 6; Red Hat Ceph Storage 7; Red Hat Ceph Storage 9; Red Hat Hardened Images.
Red Hat lists Red Hat Ceph Storage 8; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
