Overview

Affected versions of this package are vulnerable to Access Restriction Bypass via the CiliumNetworkPolicy function in validator.go file. An attacker can affect traffic on an entire Cilium cluster, potentially bypassing policy enforcement in other namespaces by creating or modifying CiliumNetworkPolicy objects in a particular namespace.

Note: This is only exploitable if the attacker has API server access.
