Description

A flaw was found in Red Hat Advanced Cluster Security for Kubernetes (RHACS). Central does not limit the depth of GraphQL queries served on the authenticated GraphQL API. An authenticated user with a valid API token can send deeply nested queries that cause excessive resource consumption in Central, resulting in a denial of service for the management plane.
