How to fix or mitigate CVE-2026-61193?

Within 24 hours, inventory all WebCenter Portal instances running versions 12.2.1.4.0 or 14.1.2.0.0 and immediately implement firewall rules or WAF policies to restrict network access to the Runtime Tools endpoint; enable enhanced monitoring and alerting on all WebCenter Portal access logs for anomalies. Within 7 days, deploy a Web Application Firewall with explicit rules blocking unauthenticated access to Runtime Tools, implement network segmentation to isolate WebCenter Portal from production Fusion Middleware instances, and disable the Runtime Tools component entirely if your organization does not use this functionality. Within 30 days, establish daily monitoring of Oracle security advisories for patch availability; if a patch is released, develop a change management plan to apply it to all affected systems; if no patch emerges within 30 days, conduct a formal risk assessment to determine whether to accept residual risk with compensating controls, accelerate migration to supported versions, or evaluate alternative solutions.
