A fix is available — apply it.

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.
