description
react-server-dom-parcel, react-server-dom-turbopack, and react-server-dom-webpack can be made to consume excessive CPU or memory through requests to Server Function endpoints. Applications are affected when they run a server using React Server Components via a supporting framework, bundler, or plugin.
mitigation
Upgrade react-server-dom-parcel to 19.0.9, 19.1.10, 19.2.9, 19.3.1; react-server-dom-turbopack to 19.0.9, 19.1.10, 19.2.9, 19.3.1; react-server-dom-webpack to 19.0.9, 19.1.10, 19.2.9, 19.3.1 or later.
fixed in 19.0.9, 19.1.10, 19.2.9, 19.3.1
