How to Detect and Exploit the React RCE (CVE-2025-55182) Using Burp Suite

The new React Remote Code Execution vulnerability (CVE-2025-55182, CVSS 10) has shaken the ecosystem. PoCs are public, attackers are scanning, and many teams are still unsure how to verify whether they’re vulnerable. In this step-by-step demo, Appsecco’s Chief Hacker, Riyaz Walikar, shows exactly how we detect and exploit the React RCE using Burp Suite, Active Scan++, and a crafted multipart payload. What’s covered in this walkthrough: • How to identify the vulnerable code path • Detecting the bug with Burp Active Scan Plus • Understanding NextAction / multipart parsing behavior • Modifying multipart boundaries for exploitation • Running a safe local RCE (calculator) before escalating to real shells • How attackers would weaponize this in the wild If you're running React Server Components or Next.js, patch immediately and don’t rely on LLM-generated “fixes” without verification. For a rapid validation pass or a deep dive into your security posture, Appsecco can help. Here is our detailed article with more detection and remediation details.   / critical-react-nextjs-security-vulnerabili...   #React #NextJS #RCE #AppSec #AISecurity #BurpSuite
