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 2.13
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.

在 search-v2-operator 中发现了一个漏洞。该漏洞允许具有特权的用户（具体为自定义资源（CR）编辑器）在未经验证的情况下操纵搜索 CR 字段，例如 imageOverride、参数和环境变量。通过利用此漏洞，攻击者可以将任意秘密挂载到搜索容器的环境中，或用攻击者控制的镜像替换容器镜像。这会导致权限提升，并可能由于 ServiceAccount 具有广泛的 impersonation（模拟）权限，从而导致整个集群被完全入侵。

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.
