CVE-2026-71467 Red Hat CVE debrief

Who should care

Organizations using search-v2-api, particularly those with federated search configurations, should be aware of this vulnerability and take steps to mitigate it. They should review their deployments, assess potential exposure, and implement necessary security measures to prevent unauthorized access to sensitive information.

Technical summary

The authentication middleware in search-v2-api unconditionally skips authentication when a request includes an 'Upgrade: websocket' header. An unauthenticated attacker can exploit this by sending a specially crafted HTTP POST request to the '/federated' endpoint, allowing access to federated search results across all configured remote managed hubs. This vulnerability affects search-v2-api and can lead to information disclosure if not properly mitigated.

Defensive priority

Organizations using search-v2-api should prioritize authentication and access control measures.

Recommended defensive actions

• Review and enhance authentication mechanisms for search-v2-api
• Implement WebSocket protocol security measures
• Monitor for suspicious activity on the /federated endpoint
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.

Evidence notes
