Summary
A flaw was found in insights-client: a compromised managed cluster (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.
Risk Assessment
The risk includes the possibility of redirecting requests to unauthorized endpoints, potentially leading to data leakage or compromise of the Insights system integrity.
Recommendation
Upgrade insights-client to a patched version and implement validation and URL encoding for ClusterID.
