How to fix or mitigate EUVD-2026-45360?

Within 24 hours: inventory all deployed VMware Avi Load Balancers and identify instances running versions 22.1.1-22.1.7, 30.1.1-30.2.6, or 31.1.1-31.2.2; segment these by criticality and external network exposure. Within 7 days: implement Layer 3 firewall rules restricting access to Avi Controller management ports (22, 443) to only authorized administrator networks and jump hosts; enable detailed audit logging on all controller API calls and authentication attempts; scan historical logs for signs of unauthorized access or exploitation. Within 30 days: monitor VMware/Broadcom security bulletins for a released patch; develop a staged upgrade plan with roll-out windows; if patch timeline extends beyond organizational risk tolerance, evaluate failover to alternative load-balancing platforms or temporary removal of external-facing Avi instances from production.
