CWE-532

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.
