LLMs Cannot Reliably Detect Vulnerabilities in JavaScript - arxiv.org/pdf/2512.01255 Researchers have proposed numerous methods to detect vulnerabilities in JavaScript, especially those assisted by Large Language Models (LLMs). However, the actual capability of LLMs in JavaScript vulnerability detection remains questionable, necessitating systematic evaluation and comprehensive benchmarks. Unfortunately, existing benchmarks suffer from three critical limitations: (1) incomplete coverage, such as covering a limited subset of CWE types (2) underestimation of LLM capabilities caused by unreasonable ground truth labeling (3) overestimation due to unrealistic cases such as using isolated vulnerable files rather than complete projects.

React2Shell (CVE-2025-55182) has been widely discussed in the security and engineering communities this week. It is a CVSS 10 vulnerability in React Server Components affecting React 19 and frameworks that depend on those packages, including recent versions of Next.js. Key points for teams assessing exposure: • Vulnerable RSC packages: react-server-dom-webpack, -turbopack, -parcel • Recent Next.js versions include these packages by default • Patched versions for React and Next.js are available • AWS, Cloudflare, and GCP have published WAF rules • Static sites do not execute RSC and are not affected This issue matters because the affected RSC packages are included by default in many React 19 and Next.js deployments, even when teams are not intentionally using RSC features. Exploitability varies by configuration, so verification is important. This situation is evolving rapidly as researchers continue to analyze real world behavior. We will update our blog as new information becomes available. Full analysis: averlon.ai/blog/react2shell-… #React2Shell #CVE202555182 #SoftwareSecurity #JavaScriptSecurity #RSC

[LAB] Client-Side Prototype Pollution via Browser APIs This lab is vulnerable to DOM XSS via client-side prototype pollution. The website's developers have noticed a potential gadget and attempted to patch it. However, you can bypass the measures they've taken. Here’s what you’ll do: ✅ Inject arbitrary properties into Object.prototype 🔍 Identify exploitable gadget properties 💥 Trigger alert() using your payload You can go hands-on manually or use DOM Invader to guide your attack. This lab is based on real vulnerabilities uncovered by our own research team.
