Name of the Vulnerable Software and Affected Versions Cilium versions prior to 1.11.15 Cilium versions prior to 1.12.8 Cilium versions prior to 1.13.1

Description Cilium may misattribute the source IP address of traffic to a cluster, identifying external traffic as coming from the host on which Cilium is running. As a consequence, network policies for that cluster might be bypassed, depending on the specific network policies enabled. This issue only manifests when Cilium is routing IPv6 traffic and NodePorts are used to route traffic to pods. IPv6 and endpoint routes are both disabled by default.

Recommendations For versions prior to 1.11.15, update to version 1.11.15 or later. For versions prior to 1.12.8, update to version 1.12.8 or later. For versions prior to 1.13.1, update to version 1.13.1 or later. As a temporary workaround, consider disabling IPv6 routing.
