What it does
Browser and V8 exploitation playbook. Use when exploiting JavaScript engine vulnerabilities including JIT type confusion, incorrect bounds elimination, and V8 sandbox bypass to achieve renderer RCE and sandbox escape in Chrome/Chromium.
SKILL: Browser / V8 Exploitation, Expert Attack Playbook
AI LOAD INSTRUCTION: Expert V8/Chrome exploitation techniques. Covers V8 compilation pipeline, JIT type confusion, addrof/fakeobj primitives, ArrayBuffer corruption, WASM RWX pages, V8 sandbox (pointer compression), and Chrome sandbox escape overview. Distilled from ctf-wiki browser sections, Project Zero research, and CTF competition patterns. Base models often confuse V8 object representation details and miss the pointer compression barrier.

1. V8 ARCHITECTURE
Compilation Pipeline
JavaScript Source
↓ Parser
AST (Abstract Syntax Tree)
↓ Ignition
Bytecode (interpreted, profiling)
↓ Sparkplug (non-optimizing baseline, V8 ≥ 9.1)
Baseline code (fast startup)
↓ Maglev (mid-tier, V8 ≥ 10.2)
Mid-optimized code
↓ TurboFan (optimizing JIT)
Optimized machine code (with speculative optimizations)
↓ Deoptimization (if speculation fails)
