Description OSIDB Bzimport 2026-01-15 20:02:00 UTC 
Istio through 1.28.2 allows iptables rule injection for changing firewall behavior via the traffic.sidecar.istio.io/excludeInterfaces annotation. NOTE: the reporter's position is "this doesn't represent a security vulnerability (pod creators can already exclude sidecar injection entirely)."
