What is CVE-2026-71475?
CVE-2026-71475 is a medium-severity path traversal vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.13, published on 11 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official 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.
