In version 0.9.2 and earlier, a tenant who can create a controller-owned workload can use the openfeature.dev/featureflagsource annotation with NAMESPACE/NAME syntax to reference a FeatureFlagSource or InProcessConfiguration in another namespace. On multi-tenant clusters that use namespaces as trust boundaries, the cluster-scoped operator reads that resource and materializes spec.envVars literal values, spec.httpSyncBearerToken, sync URIs, and supporting ConfigMaps into the tenant's workload. Single-tenant clusters are not impacted, secretKeyRef and configMapKeyRef values remain namespace-local, and creating a FeatureFlagSource is not required."}],"source":{"advisory":"GHSA-398h-7f66-3h4p","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-18T14:36:49.070602Z","id":"CVE-2026-54495","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-18T14:43:51.856Z"}}]}}
