CVE-2025-67499: CNA Plugins Portmap nftables backend can intercept non-local traffic
(updated )
Containers (i.e. kubernetes pods) that request HostPort forwarding can intercept all traffic destined for that port. This requires that the portmap plugin be explicitly configured to use the nftables backend. (The iptables backend is the default.)
