Aug 26 PATCH SHIPPED — CVE-2026-71475 (Red Hat Advanced Cluster Management for Kubernetes 2.13). Fixed in Red Hat Advanced Cluster Management for Kubernetes 2.13 1787259125.
Sep 2 RESCORED — CVE-2026-71475 (Red Hat Advanced Cluster Management for Kubernetes 2.13). CVSS 5 → 6.8 (NVD).
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.
