Affected versions of this package are vulnerable to Access Restriction Bypass. Under certain conditions, ICMP Echo Request sent to a Cilium endpoint from an actor (either a pod or a cluster host or a remote host) may bypass a network policy which disallows access from the actor to the endpoint, but allows from the endpoint to the actor. This does not apply to UDP and TCP traffic.
