Securing the Modern Web - React and Next.js Applications [ React2Shell CVE-2025-55182 (React) and CVE-2025-66478 (Next.js) ]
Securing the Modern Web - React and Next.js Applications [ React2Shell CVE-2025-55182 (React) and CVE-2025-66478 (Next.js) ] The evolution of web development has shifted significant complexity from the client to the server, particularly with the rise of React Server Components (RSC) and Next.js . While these technologies offer substantial performance benefits, they also introduce new attack vectors that challenge traditional security assumptions. The recent emergence of the React2Shell vulnerability and the sophisticated EtherRAT malware serves as a critical reminder that modern cloud-native attacks often chain subtle framework behaviors into devastating exploits. Understanding the React2Shell Vulnerability The React2Shell vulnerability, tracked under CVE-2025-55182 (React) and CVE-2025-66478 (Next.js), represents a high-impact Remote Code Execution (RCE) flaw. It specifically targets the Flight protocol used by React Server Components to serialize data between the server ...
