NVD Description

Note: Versions mentioned in the description apply only to the upstream hubble-ui package and not the hubble-ui package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to version 1.13.4, when Gateway API is enabled in Cilium, the absence of a check on the namespace in which a ReferenceGrant is created could result in Cilium unintentionally gaining visibility of secrets (including certificates) and services across namespaces. An attacker on an affected cluster can leverage this issue to use cluster secrets that should not be visible to them, or communicate with services that they should not have access to. Gateway API functionality is disabled by default. This vulnerability is fixed in Cilium release 1.13.4. As a workaround, restrict the creation of ReferenceGrant resources to admin users by using Kubernetes RBAC.
