WCAG Accessibility Scanner (ZAP + Selenium + axe-core)

This script allows you to automatically scan the accessibility (WCAG) of web pages discovered by OWASP ZAP, using Selenium and axe-core.

Features

• Accepts an exported file from ZAP (.json, .xml, .html, .txt) containing URLs.
• Extracts and deduplicates the list of web pages.
• Runs axe-core accessibility tests on each page via Selenium (headless Chrome by default).
• Computes an accessibility score from 0 to 100 for each page and an overall average score.
• Generates detailed reports on a new HTML page, including:
  • The score per page
  • Violations grouped by impact (minor, moderate, serious, critical)
  • Top accessibility issues with links to documentation

Requirements

• Python 3.8+
• Google Chrome installed

Install dependencies

pip install selenium webdriver-manager axe-selenium-python beautifulsoup4 lxml

Usage

Basic

python zap_wcag_accessibility.py

You will be prompted to provide the path to the ZAP output file.

With options

python zap_wcag_accessibility.py --input zap_report.json --max-pages 50

Common arguments

• --input, -i → Path to ZAP report or .txt file with URLs
• --max-pages → Maximum number of pages to scan (default: 100)
• --headless/--no-headless → Run browser in headless mode (default: headless)
• --page-wait → Seconds to wait after page load (default: 5)
• --implicit-wait → Selenium implicit wait in seconds (default: 2)
• --out-prefix → Prefix for generated report files (default: report_accessibilita)

Output

A website will be opened and the html file will be saved:

• accessibility_report_YYYYMMDD_HHMMSS.html → structured HTML page with scores and violations
