CVE-2026-66785Source published Source updated
A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption. This is an Important vulnerability in Red Hat Advanced Cluster Management for Kubernetes. This could lead to unauthorized data interception or redirection within the multi-cluster environment.
