React2Shell is a high-performance vulnerability scanner written in Go, specifically designed to detect Server-Side Remote Code Execution (RCE) vulnerabilities in Next.js applications (CVE-2025-55182 & CVE-2025-66478).
This tool improves upon existing proof-of-concept scripts by leveraging Go's native concurrency (Goroutines) and integrating automated reconnaissance via Subfinder.
Scan a single domain (automatic subdomain discovery): ./react2shell -u target.com
Scan a list of targets: ./react2shell -l targets.txt -threads 50
-u Target URL or Domain. -l Path to a file containing list of hosts. -threads Number of concurrent workers (default: 20).
