✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: No product-side mitigation is required while Zanzana remains disabled, which is the default. If Zanzana has been turned on, do not use ListUsers results as an access-control decision; use Check for each user and object until Grafana vendors OpenFGA 1.18.1 or later. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
