Overview
Affected versions of this package are vulnerable to Access Control Bypass in the handling of internal service references by the Gateway API provider. An attacker can gain unauthorized dynamic configuration write access by creating or updating an HTTPRoute that targets rest@internal, even when insecure exposure is disabled. This is only exploitable if the Kubernetes Gateway API provider is enabled, the REST provider is enabled, the REST provider is not exposed insecurely, a shared Gateway allows tenant namespaces to attach HTTPRoute resources, and the attacker can create or update HTTPRoute resources in an allowed tenant namespace.
