Denial of Service Vulnerability in React Server Components

React Server Components의 여러 패키지에서 서비스 거부(DoS) 취약점이 발견되어, 악의적으로 조작된 HTTP 요청 시 메모리 부족 또는 과도한 CPU 사용이 발생할 수 있습니다. 영향을 받는 버전은 19.0.0부터 19.2.5까지이며, 19.0.6, 19.1.7, 19.2.6 버전에서 패치가 적용되었습니다. React 서버 기능을 사용하지 않거나 관련 번들러를 사용하지 않는 앱은 영향을 받지 않습니다. 즉시 패치된 버전으로 업데이트할 것을 권고합니다.
