By mapping exploit chains from initial fingerprinting to dangerous execution sinks like child_process and eval, you can identify prototype pollution and SSTI vulnerabilities that lead to remote code execution in Node.js web applications.

Prototype pollution leads to remote code execution by allowing attackers to manipulate global object prototypes, which can then be leveraged to inject payloads into template engines or trigger dangerous sinks like child_process and eval.

Yes, this Node.js vulnerability hunting approach works with Fastify, NestJS, and Koa, applying exploit chain mapping and RCE sink detection across these frameworks in addition to standard Express applications.

Express trust proxy misconfiguration is an insecure setting that fails to properly validate proxy headers, creating security flaws by allowing attackers to spoof IP addresses and bypass access controls to reach internal endpoints.

The best way to detect SSTI vulnerabilities in Node.js template engines is to apply robust fingerprinting and inject targeted payloads into EJS, Pug, and Handlebars templates to identify potential environment exfiltration pathways.

You need to map exploit chains when testing Node.js targets for RCE because initial entry points like prototype pollution often require multiple linked steps to reach dangerous execution sinks like child_process or eval for successful code execution.
