CVE-2026-54495
Published:September 17, 2026
Updated:September 22, 2026
The OpenFeature Operator allows users to expose feature flags to applications. 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.
