Description
A denial of service issue in React Server Components allows an attacker to disable a web application by exhausting server resources. This is triggered by sending specially crafted HTTP requests to server function endpoints, which can lead to server crashes, out-of-memory exceptions, or excessive CPU usage. Exploitation requires a specific architectural setup.
Recommendations
Update react-server-dom-webpack, react-server-dom-parcel, and react-server-dom-turbopack to versions 19.0.6, 19.1.7, or 19.2.6.
