Vendor Workaround
To mitigate this vulnerability, ensure the `FEATURE_FEDERATED_SEARCH` is disabled if not actively used. This feature is off by default in standard deployments of Red Hat Advanced Cluster Management for Kubernetes. For Global Hub deployments where `FEATURE_FEDERATED_SEARCH` is enabled by default, consider restricting network access to the `search-v2-api`'s `/federated` endpoint to trusted clients.

| Description | A flaw was found in search-v2-api. The authentication middleware in the affected component 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 with the `Upgrade: websocket` header. This allows the attacker to bypass authentication and access federated search results across all configured remote managed hubs, leading to information disclosure. | |
