      "value": "HyperDX before 2.31.0 contains a server-side request forgery vulnerability that allows authenticated team members to direct the server to arbitrary internal destinations by supplying a caller-controlled host parameter to the ClickHouse proxy test endpoint with no URL validation or allowlist enforcement. Attackers can exploit the reflected error responses from the endpoint to disclose internal service response bodies, enabling access to internal APIs, container services, and cloud provider metadata endpoints."

      "value": "HyperDX anterior a la versión 2.31.0 contiene una vulnerabilidad de falsificación de petición del lado del servidor que permite a miembros del equipo autenticados dirigir el servidor a destinos internos arbitrarios al proporcionar un parámetro de host controlado por el llamador al endpoint de prueba del proxy de ClickHouse sin validación de URL ni aplicación de lista de permitidos. Los atacantes pueden explotar las respuestas de error reflejadas del endpoint para divulgar cuerpos de respuesta de servicios internos, lo que permite el acceso a APIs internas, servicios de contenedores y endpoints de metadatos de proveedores de la nube."
