      "value": "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."

    {
      "lang": "es",
      "value": "Se encontró una vulnerabilidad en search-v2-api. El middleware de autenticación en el componente afectado omite incondicionalmente la autenticación cuando una solicitud incluye una cabecera ’Upgrade: websocket’. Un atacante no autenticado puede explotar esto enviando una solicitud HTTP POST especialmente diseñada al endpoint ’/federated’ con la cabecera ’Upgrade: websocket’. Esto permite al atacante eludir la autenticación y acceder a los resultados de búsqueda federada en todos los hubs remotos gestionados configurados, lo que lleva a la revelación de información."
