An insecure neighbor: how a vulnerability chain led to an isolation bypass in cloud infrastructure
Kaspersky researchers chained flaws in Kubernetes, Konnectivity, and the overlay network to break cloud tenant isolation and achieve RCE on neighbouring tenants — a concrete demonstration that shared-infrastructure trust boundaries remain fragile.

A Kaspersky expert presents a cloud isolation bypass case honored at Russian Pentest Award 2026. Learn how vulnerabilities in Kubernetes, Konnectivity, and the overlay network lead to RCE and compromise of other tenants' services.
Editorial Analysis
European enterprises migrating workloads to multi-tenant Kubernetes platforms face the risk that a single neighbour's compromise can cascade into cross-tenant data access, with GDPR and NIS2 implications.
Conduct an isolation-assurance review of your managed Kubernetes environments, focusing on Konnectivity proxy exposure, network-policy completeness, and overlay-network segmentation.
A demonstrated cloud tenant-isolation bypass underscores that shared Kubernetes infrastructure carries residual cross-customer risk requiring explicit architectural controls.
