PHP2Shell and Node2Shell: Find, Fix, and Verify Across Your Web Apps and APIs

PHP2Shell and Node2Shell represent critical runtime vulnerabilities affecting PHP and Node.js respectively, enabling remote code execution across any application or API built on vulnerable versions. Crucially, exploitation was observed before patches were available, meaning organizations relying on reactive patch cycles were already exposed. This highlights the danger of running internet-facing applications on unvalidated runtime versions without compensating controls. The incidents underscore that web application runtimes are high-value attack surfaces requiring the same rigorous patch and vulnerability lifecycle management as operating systems and network devices.
