Detection Logic

We test for all three major types of XSS by injecting polyglots and monitoring the browser's execution context.

01

Reflected XSS

We inject payloads into URL parameters and check if they are reflected back in the HTML response without proper escaping.

02

Stored XSS

We test input forms (like comments) to see if injected scripts are saved to the database and executed on subsequent page loads.

03

DOM-Based XSS

We use a headless browser to analyze client-side JavaScript execution, detecting unsafe handling of sources (URL) and sinks (innerHTML).

Polyglot Payloads

Uses advanced payloads designed to break out of multiple contexts (HTML, JS, Attributes) simultaneously.

Browser Simulation

Executes tests in a real Chrome environment to catch complex DOM-based vulnerabilities that static scanners miss.

WAF Bypass

Includes encoded and obfuscated payloads to test the resilience of your Web Application Firewall.
