How to fix?

There is no fixed version for RHEL:8 grafana-azure-monitor.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grafana-azure-monitor package and not the grafana-azure-monitor package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

An authenticated attacker with Editor access or alert.instances.external:write can submit an external Alertmanager alert containing a controlled generatorURL. The attacker is authorized to create the alert, but not to execute script in another user's Grafana session.

Grafana renders alert.generatorURL directly as the Alert Details See source LinkButton href without URL-scheme sanitization or a safe-protocol allowlist. The click interceptor's :// heuristic can be bypassed by placing :// inside a JavaScript comment. When a user with read access clicks See source, the browser executes attacker-controlled JavaScript in the Grafana origin with the clicking user's permissions.
