CVE-2026-66780— Submariner-operator: submariner-operator: flat broker trust model grants every spoke full crud on all endpoints, secrets, and endpointslices in broker namespace

Quick assessment

Affected
Red Hat Red Hat Advanced Cluster Management for Kubernetes 2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 submariner-operator 组件中发现了一个缺陷。分配给已加入集群的 Role 拥有过高的权限。这使得遭到入侵的集群能够修改网络配置，特别是可以覆盖其他集群的端点信息。攻击者因此可以重定向集群间的隧道流量，从而在整个集群网格中实施中间人（MITM）攻击。

Vulnerability Title
Submariner-operator: submariner-operator: flat broker trust model grants every spoke full crud on all endpoints, secrets, and endpointslices in broker namespace
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the submariner-operator component. The `submariner-k8s-broker-cluster` Role, which is assigned to joined clusters, possesses excessive permissions. This allows a compromised cluster to alter network configurations, specifically by overwriting other clusters' endpoint information. Consequently, an attacker can redirect inter-cluster tunnel traffic, enabling a Man-in-the-Middle (MITM) attack across the entire cluster mesh.
