Official description

NVD · unedited

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.

Technical summary

dbcve analysis

How this class of weakness works · CWE-22

A file path is built from user input without being confined, so sequences like “../” let an attacker step outside the intended directory. That can expose configuration, credentials, or source code, and in the worst case lets an attacker write files where they shouldn't. A durable fix resolves and canonicalises the path, then rejects anything that escapes a known-safe base directory.

CVE-2026-71475 is a trust boundary inversion in a hub-and-spoke insights architecture. The hub authenticates spoke requests, then takes the spoke's self-reported ClusterID and uses it as a URL path component when redirecting API calls to the central Insights service — without re-validating that value. This is not merely a missing URL encoding issue; it's a design flaw where the authenticated channel carries untrusted data that the server uses for routing decisions. The critical question that determines actual impact: does the Insights API backend authorize requests based on the ClusterID in the URL path, or does it use the authenticated session identity derived from the hub-spoke trust relationship? If the backend enforces cluster-level isolation using the path parameter for authorization, this vulnerability enables cross-cluster data disclosure — a compromised spoke becomes a pivot to any cluster the hub has ever managed. If the backend uses session context, the impact is substantially lower. Given that a compromised spoke implies an attacker with authenticated API access and code execution, the incremental risk depends on whether they can now access data outside their cluster boundary. The CVSS of 5 likely reflects an analyst assuming the backend uses session-level authorization — but that assumption must be verified, not presumed. Prioritize these actions: First, determine whether your Insights API backend authorizes on the ClusterID path parameter or on session identity; this single question dominates your risk posture. Second, audit the hub's routing logic to confirm ClusterID is validated against an internal registry before URL interpolation. Third, treat any 'compromised spoke' as an active authenticated threat vector — the attacker has valid credentials, not just local persistence, and can enumerate ClusterIDs at scale if the backend permits path-based access. Note the architectural blind spot: standard scoring metrics don't capture the temporal exposure window in hub-and-spoke. The CVE publishes, the patch drops, but thousands of spokes must update before the exposure closes. This lag — not the individual interaction severity — is the compounding risk. Track mean time to remediation across your fleet; that's the real metric.
