Cross-Site Scripting (XSS) Parameter Scanner

"Blazing fast parameter analysis and XSS scanner with DOM, reflected, and blind verification."

▶ Scan with XSS Scanner
Overview

Cross-Site Scripting (XSS) remains one of the most common and damaging web application vulnerabilities. XSS Scanner is an advanced parameter analysis and dedicated injection engine. It parses endpoints, discovers hidden query and body parameters, and executes contextual payload tests to confirm exploitability without manual intervention.

Unlike naive regex scanners, XSS Scanner tests the DOM execution context, checks for HTML entity encoding bypasses, detects filter behavior, and validates whether payloads actually trigger in modern browser runtimes. It handles reflected XSS, stored injection points, and client-side DOM vulnerabilities with minimal false positives.

XSS Scanner works seamlessly when paired with HTTP Prober for live URL discovery and Vulnerability Scanner for broad CVE template coverage. It dives deep into input parameters to verify if user-supplied input can break out of JavaScript or HTML tags.
