CVE-2026-71470— Acm-search-v2-rhel9: search-v2-operator: search cr imageoverride/arguments/envvar flow unsanitized into pods running impersonating sa

Quick assessment

Affected
Red Hat Red Hat Advanced Cluster Management for Kubernetes 2.11
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Stolostron search-v2-operator是Stolostron组织的一个云计算搜索服务管理组件。 Stolostron search-v2-operator存在处理逻辑错误漏洞，该漏洞源于对Search CR字段（如imageOverride、arguments和环境变量）的验证不当，可能导致权限提升，并因ServiceAccount的广泛模拟权限造成集群完全被破坏。

Vulnerability Title
Acm-search-v2-rhel9: search-v2-operator: search cr imageoverride/arguments/envvar flow unsanitized into pods running impersonating sa
Source: CVE Program / CVE List V5
Vulnerability 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.
