## Multi-tenancy considerations

> [!IMPORTANT]
> OFO installs cluster-wide and resolves `FeatureFlagSource` / `InProcessConfiguration` resources across namespaces (see [annotation syntax](docs/annotations.md)). On clusters that treat namespaces as trust boundaries between tenants, one tenant can cause OFO to read these resources from another tenant's namespace. See [GHSA-398h-7f66-3h4p](https://github.com/open-feature/open-feature-operator/security/advisories/GHSA-398h-7f66-3h4p) for the threat model, mitigations, and roadmap.

A future release will introduce explicit cluster-scoped `ClusterFeatureFlagSource` / `ClusterInProcessConfiguration` and remove implicit cross-namespace resolution. Per-tenant operator install is tracked in [#795](https://github.com/open-feature/open-feature-operator/issues/795).
