React/Next.js CVE-2025-55182 Vulnerability Analysis

A critical Remote Code Execution vulnerability (CVE-2025-55182, CVSS 10.0) affecting React/Next.js was disclosed and is present in many Web3 applications; exploit consequences include server compromise, sensitive data or private key exfiltration, and injected JavaScript wallet drainers. The advisory lists vulnerable Next.js and React versions, provides quick self-checks (window.next.version and npm ls react), and gives remediation and follow-up steps (upgrade to patched versions, verify lockfiles/node_modules, rebuild/deploy, rotate secrets, review logs); additional CVEs affecting React Server Components (DoS and source-code exposure) were later disclosed, and immediate upgrades are strongly recommended.
