Recommended ActionAI
Within 24 hours, inventory every HFM 11.2.26.0.000 deployment, identify which Security-component endpoints are reachable from outside trusted network segments (including HFM web/application tiers and any exposed TCP service ports), and block that reachability at the firewall, load balancer, or cloud security group; since no vendor patch is available, treat network isolation as the primary control and, where the service must remain reachable, force access through an MFA-enforcing VPN or authenticating reverse proxy. …
