# SKILL: Prototype Pollution Advanced — RCE & Gadget Exploitation

> **AI LOAD INSTRUCTION**: Advanced prototype pollution escalation. Covers server-side RCE via template engines (EJS, Pug, Handlebars), Node.js child_process gadgets, client-side script gadgets, filter bypass patterns, and systematic detection. Load [../prototype-pollution/SKILL.md](../prototype-pollution/SKILL.md) first for fundamentals (merge sinks, `__proto__` vs `constructor.prototype`, basic probes).

## 0. RELATED ROUTING

- [prototype-pollution](../prototype-pollution/SKILL.md) — **LOAD FIRST** for PP fundamentals, merge-sink detection, basic probes
- [ssti-server-side-template-injection](../ssti-server-side-template-injection/SKILL.md) — template engine RCE context (PP often triggers through template gadgets)
- [xss-cross-site-scripting](../xss-cross-site-scripting/SKILL.md) — client-side PP gadgets ultimately achieve XSS

### Advanced Reference

Load [KNOWN_GADGETS.md](./KNOWN_GADGETS.md) for the comprehensive gadget table by framework/library with polluted properties, trigger conditions, impact, and affected versions.
