Описание
It was found that the fix addressing CVE-2025-55184 in React Server Components was incomplete and does not prevent a denial of service attack in a specific case. React Server Components versions 19.0.2, 19.1.3 and 19.2.2 are affected, allowing unsafe deserialization of payloads from HTTP requests to Server Function endpoints. This can cause an infinite loop that hangs the server process and may prevent future HTTP requests from being served.
A flaw was found in React Server Components. This vulnerability allows a denial of service via unsafe deserialization of payloads from HTTP (Hypertext Transfer Protocol) requests to Server Function endpoints. A malicious HTTP request can be crafted and sent to any App Router endpoint that, when deserialized, can cause the server process to hang and consume CPU. This can result in denial of service.
This CVE has been issued as a complete fix for CVE-2025-55184 which was incomplete with initial fix.
