How to fix?

Upgrade Centos:8 grafana to version 0:9.2.10-7.el8_9 or higher.

NVD Description

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

Grafana is validating Azure AD accounts based on the email claim.

On Azure AD, the profile email field is not unique and can be easily modified.

This leads to account takeover and authentication bypass when Azure AD OAuth is configured with a multi-tenant app.
