High Fidelity Detection Mechanism for RSC/Next.js RCE (CVE-2025-55182 & CVE-2025-66478) › Searchlight Cyber
This morning, an advisory was released for Next.js about a vulnerability that leads to RCE in default configurations, with no prerequisites. The root cause of this issue lies in React Server Components, which Next.js utilizes. Over the last day, we have noticed an incredible amount of incorrect PoCs floating around on GitHub that do not
Real-World React: Designing Frontend Architectures That Survive Production | Workshops | Faris Aziz
Most React workshops focus on building features. This one focuses on keeping them alive. In production, React applications fail in ways that local environments never show: partial outages, slow dependencies, silent errors, broken rollouts, and performance regressions that only appear under real traffic. This workshop is a practical, architecture-first walkthrough of how experienced teams design React systems that stay resilient, observable, and scalable long after the first release. We will explore how component architecture, reconciliation in practice, and runtime failure patterns shape performance and operability far more than memoization tricks or framework features. Using React and Next.js as shared reference points, we will work through concrete patterns for failure recovery, error containment, safe rollouts, and post-deployment confidence. This is a hands-on, experience-driven workshop based on real production constraints, tradeoffs, and lessons learned from operating large React applications at scale. Attendees will leave with a mental model for building frontend systems that can fail safely, recover quickly, and ship continuously without fear. Most of the workshop is framework and library-agnostic, but we'll use React and Next.js as our common ground for communication and examples. This is not an exhaustive masterclass; it's a conversation starter and experience share to jumpstart your journey toward battle-tested software architecture.

Critical Security Vulnerability in React Server Components – React
react.devI am very proud of the team for the runtime level mitigation we rolled out to @deno_land Deploy for this. It's very precise, very fast, and way less prone to false positives than the WAF based block. All versions of React are safe now when running on Deno Deploy - yay to vertical integration!
