The AlmaLinux security team deemed this advisory irrelevant for AlmaLinux:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream grafana-selinux package and not the grafana-selinux package as distributed by AlmaLinux.
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.
