# Advanced XSS Polyglot
This payload is designed to execute across numerous HTML/JS contexts and evade standard filters by mixing comment styles, breaking out of tags, and leveraging lowercase event handlers. Use cases include testing various input sanitization weaknesses and filters.
# Crafting Tips
- Mix encoding methods (URL, HTML entities, Unicode) to sneak past blacklists.
- Use HTML breaking elements (`</textarea>`, `</script>`, etc.) to escape confined contexts.
- Leverage less common event handlers (e.g., `onauxclick`, `ontoggle`) for advanced bypasses.
