Description
Incomplete Cleanup (CWE-459) in Elastic Cloud on Kubernetes (ECK) can lead to unauthorized access via Privilege Abuse (CAPEC-122). Authentication credentials persist after a cross-namespace association has been denied by RBAC enforcement, allowing a low-privileged tenant to retain unauthorized read access to the associated Elasticsearch cluster.
