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.

Remediation

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.
