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

Solution
Sanitize or encode user-controlled input used in API URL paths to prevent redirection.
  • Validate and encode the ClusterID before using it in the URL path.
  • Ensure all user-supplied data in URL paths is properly escaped.
  • Review and update API request handling logic.
