Resource exhaustion from customer-configurable connection limits
Published May 6, 2026 · Updated May 6, 2026
Cisco Crosswork Change Automation and Network Services Orchestrator are not affected by a security vulnerability under this record. Cisco determined that incoming connection limits are customer-configurable capacity controls rather than inadequate security rate limiting. Large connection volumes can still exhaust provisioned resources and require a manual reboot, but Cisco classifies that outcome as a sizing and resource-management condition rather than attacker-triggered security impact.
