One-stop solution for security researchers, penetration testers, and bug bounty hunters. Featuring 900+ curated payloads, advanced bypass techniques, and real-time payload generation.
Understanding Cross-Site Scripting (XSS) and how security researchers use XSS payloads
An XSS payloads list is a collection of malicious scripts used to test web applications for cross-site scripting vulnerabilities. XSSNow provides over 1000+ curated XSS payloads including basic alert payloads, event handler exploits, SVG-based XSS, and polyglot payloads that work across multiple contexts.
Our XSS cheat sheet serves as a comprehensive reference for penetration testers and bug bounty hunters. It includes DOM XSS payloads, reflected XSS payloads, stored XSS payloads, and advanced filter bypass techniques for WAFs like Cloudflare, AWS WAF, and Akamai.
The XSS payload generator creates context-aware cross-site scripting payloads based on your target. Generate XSS payloads for HTML body, JavaScript context, URL parameters, and HTML attributes with automatic WAF bypass encoding and filter evasion techniques.
Non-persistent XSS where the payload is reflected from the server in the HTTP response
Persistent XSS where the payload is stored on the server and executed for all users
Client-side XSS where the vulnerability exists in JavaScript code manipulating the DOM
