What is CVE-2026-71470?
CVE-2026-71470 is a critical vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11, published on 19 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
A flaw was found in the search-v2-operator. This vulnerability allows a privileged user, specifically a Custom Resource (CR) editor, to manipulate Search CR fields such as imageOverride, arguments, and environment variables without proper validation. By exploiting this, an attacker can mount arbitrary secrets into a search container's environment or replace the container image with an attacker-controlled one. This leads to privilege escalation and can result in a full cluster compromise due to the ServiceAccount's extensive impersonation permissions.
