Professional-grade scanning with confidence scoring and WAF bypass detection
Each vulnerability is assigned a confidence score based on payload execution probability, context analysis, and response behavior.
Automatically detects Web Application Firewalls and attempts bypass techniques including encoding, obfuscation, and case variation.
Detects XSS in different contexts: HTML, JavaScript, CSS, URL, and attribute contexts with specialized payloads for each.
Comprehensive payload database covering Reflected, Stored, DOM, Blind XSS, and Template Injection vulnerabilities.
Export scan results in multiple formats including JSON, CSV, and HTML reports for documentation and sharing.
Watch the scanning process in real-time with detailed logging of each test, response analysis, and detection events.
XSS Scanner Pro uses a multi-layered approach to vulnerability detection. Our confidence scoring system analyzes payload execution probability, response patterns, and context to provide accurate results.
Probes target with benign requests to identify WAF presence and type
Tests 200+ payloads across all XSS categories and contexts
Assigns confidence based on payload type, context, and response
If WAF detected, attempts encoding and obfuscation bypasses
Always follow responsible disclosure practices when discovering vulnerabilities. Never test systems without explicit permission from the owner.
