Mitigation checklist

Recommended fix / mitigation
  • 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.
