Overview
react-server-dom-webpack is a React Server Components bindings for DOM using Webpack. This is intended to be integrated into meta-frameworks. It is not intended to be imported directly.
Affected versions of this package are vulnerable to Arbitrary Code Injection via unsafe deserialization of RSC payloads from HTTP requests to Server Function endpoints. An unauthenticated attacker can execute arbitrary code on the server by sending malicious HTTP requests.
Note:
Serverless applications and applications that do not use a framework, bundler, or bundler plugin that supports React Server Components are not affected by this vulnerability.
