How to fix?

There is no fixed version for RHEL:8 rhceph/grafana-rhel9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rhceph/grafana-rhel9 package and not the rhceph/grafana-rhel9 package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).
