## Critical RCE Vulnerability in React Server Components Exposes Next.js, Vercel Issues Automated Patch
A critical remote code execution (RCE) vulnerability has been identified within React Server Components, directly impacting major frameworks like Next.js. The flaw, stemming from insecure deserialization in the React Flight protocol, enables unauthenticated attackers to execute arbitrary code on the server. This vulnerability was discovered in the project `ai-interviewer-analyzer-main` on Vercel, highlighting a potential widespread exposure for applications built with these technologies.

The security advisories are formally tracked as GitHub Security Advisory GHSA-9qr9-h5gf-34mp, React's CVE-2025-55182, and Next.js's CVE-2025-66478. In response, Vercel has automatically generated a pull request for affected projects to aid in patching efforts. However, the company explicitly states it cannot guarantee the patch's comprehensiveness and warns it may contain mistakes, urging developers to conduct additional reviews before merging.

The discovery places immediate pressure on development teams using React Server Components and Next.js to audit and secure their deployments. The automated patch, while a rapid response, underscores the inherent risk in server-side rendering frameworks where deserialization flaws can lead to full server compromise. This incident triggers urgent scrutiny across the React ecosystem, potentially affecting thousands of production applications until the vulnerability is fully mitigated.
