Summary

A flaw was found in the `search-v2-operator` component. A user with specific administrative permissions on a managed cluster can exploit a vulnerability that allows them to inject arbitrary configuration data.

This manipulation can override critical settings, leading to the replacement of container images. This ultimately results in container image injection on the managed cluster, potentially compromising its integrity.

Important: This flaw in Red Hat Advanced Cluster Management for Kubernetes allows a user with `patch managedclusteraddons` permission on a managed cluster to achieve container image injection.

By manipulating the `addon.open-cluster-management.io/values` annotation on a `ManagedClusterAddOn`, an attacker can override Helm values, leading to privilege escalation and arbitrary code execution on the managed cluster. Red Hat severity: Important — CVSS 8.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N).
