React is an open-source JavaScript library developed by Meta for building user interfaces. Recently, Meta released a critical security advisory (CVE-2025-55182, CVSS: 10.0), indicating that React Server Components contain a remote code execution vulnerability. Due to a security weakness in how React parses data sent to React Server Function endpoints, attackers may trigger arbitrary code execution through specially crafted payloads without requiring authentication.
