When uploading a device image, Traccar uses that `uniqueId` to build the filesystem path without enforcing that the resolved path stays under the media root. This allows writing files outside the media directory. As of time of publication, it is unclear whether a fix is available."}, {"lang": "es", "value": "Las versiones del sistema de seguimiento GPS de c\u00f3digo abierto Traccar hasta la 6.11.1 inclusive contienen un problema en el que los usuarios autenticados que pueden crear o editar dispositivos pueden establecer el 'uniqueId' de un dispositivo a una ruta absoluta.
