Doc Text:
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.

Description OSIDB Bzimport 2026-05-21 13:28:42 UTC
A flaw was found in RHACS Central. The GraphQL API (/api/graphql) does not enforce a maximum query depth when the schema is built. The schema includes recursive type relationships; an authenticated user can submit deeply nested queries that cause excessive resolver and database work, leading to high CPU and memory use and denial of service for Central.
