CVE-2026-71467 | BDVDB-2026-357971 Detail
Red HatRed Hat Advanced Cluster Management for Kubernetes 2.17
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.
Impact#
