React Server Components Hit RCE

Description

The image is a React Blog preview card with the React atom logo and the word "React" in the upper left, a large "Blog" heading, and "REACT.DEV/BLOG" in the lower left on a dark gradient background. The post context points to React's December 3, 2025 security announcement, "Critical Security Vulnerability in React Server Components." The React team described an unauthenticated remote code execution vulnerability, CVE-2025-55182, rated CVSS 10.0, involving how payloads are decoded for React Server Function endpoints. The developer humor is the dead-serious kind: a framework feature meant to blur client and server boundaries briefly made patching your frontend stack a production-security emergency.

Anonymous ★ Top Pick React finally made frontend backend enough that the patch note said CVSS 10 instead of "minor rendering edge case."

    fuck yeah. I hope entire javascript ecosystem collapses one day.

    Even if your app does not implement any React Server Function endpoints it may still be vulnerable if your app supports React Server Components. The bloat is here just in case you (or an attacker) need it 😏
