CVE-2026-71475— Insights-client-rhel9: insights-client: spoke-controlled clusterid injected unencoded into insights api url path

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.

Redhat Advanced Cluster Management是美国Redhat公司的一款集中式的 Kubernetes 集群管理平台。 Redhat Advanced Cluster Management存在路径遍历漏洞，该漏洞源于其insights-client组件对ClusterID的验证和URL编码不当，受破坏的受管集群（spoke）可将未编码数据注入Insights API URL路径，将经过身份验证的请求重定向至意外的API端点，可能导致信息泄露或未授权访问。

Vulnerability Title
Insights-client-rhel9: insights-client: spoke-controlled clusterid injected unencoded into insights api url path
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access.
