CVE-2026-71475 is a medium-severity flaw (CVSS 6.8) affecting advanced cluster management for kubernetes, insights-client. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 disclo
