AI-Generated

The Elastic Cloud on Kubernetes (ECK) operator is vulnerable due to improper validation of secret references, allowing users with limited namespace permissions to exploit this flaw. By manipulating annotations, an attacker can trigger the operator to access and copy sensitive secrets from other namespaces into a location they can read, potentially leading to unauthorized data exposure. Organizations using Kubernetes, particularly those leveraging ECK, should prioritize addressing this vulnerability to safeguard against potential data leaks.

Original NVD Description

The Elastic Cloud on Kubernetes (ECK) operator reads a list of secret references from an annotation on secrets it manages, and it accepts the namespace recorded in each reference without validating that the reference is authorized for the resource being reconciled. A user whose Kubernetes permissions are limited to their own namespace can write that annotation, trigger a reconcile, and cause the operator to use its cluster-wide secret permissions to copy the contents of a secret from any other namespace into a secret the user can read.
