# SKILL: Cross-Site Scripting (XSS) — Expert Attack Playbook
> **AI LOAD INSTRUCTION**: This skill covers non-obvious XSS techniques, context-specific payload selection, WAF bypass, CSP bypass, and post-exploitation. Assume the reader already knows `<script>alert(1)</script>` — this file only covers what base models typically miss. For real-world CVE cases, HttpOnly bypass strategies, XS-Leaks side channels, and session fixation attacks, load the companion [SCENARIOS.md](./SCENARIOS.md).
## 0. RELATED ROUTING
### Extended Scenarios
Also load [SCENARIOS.md](./SCENARIOS.md) when you need:
- Django debug page XSS (CVE-2017-12794) — duplicate key error → unescaped exception → XSS
- UTF-7 XSS for legacy IE environments (`+ADw-script+AD4-`)
- HttpOnly bypass methodology — proxy-the-browser, session riding, CSRF-via-XSS
- XS-Leaks side channel attacks — timing oracle, cache probing, `performance.now()` measurement
- Session fixation via XSS — pre-set session ID before victim login
