🔍 How to Verify
Check if Vulnerable:
Check the plugin version in WordPress admin under Plugins > Installed Plugins; if version is 3.18.13 or earlier, it is vulnerable.Check Version:
In WordPress, run: wp plugin list --name=wppizza --field=version (requires WP-CLI)Verify Fix Applied:
After updating, confirm the plugin version is above 3.18.13 and test by attempting to inject a simple XSS payload (e.g., <script>alert('test')</script>) into relevant input fields to ensure it is neutralized.📡 Detection & Monitoring
Log Indicators:
- Look for unusual GET or POST requests containing script tags or JavaScript payloads in web server logs (e.g., Apache, Nginx).
Network Indicators:
- Monitor for HTTP requests with suspicious parameters like 'script' or 'onload' targeting the WPPizza plugin endpoints.
