Name of the Vulnerable Software and Affected Versions Elastic Cloud on Kubernetes (affected versions not specified)
Description An incomplete cleanup issue in Elastic Cloud on Kubernetes (ECK) allows for privilege abuse. Authentication credentials persist even after a cross-namespace association is denied by Role-Based Access Control (RBAC) enforcement. This allows a low-privileged tenant to maintain unauthorized read access to the associated Elasticsearch cluster.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
