<h3>Privacy and Data Collection</h3>
VMP Fence respects your privacy and follows WordPress.org guidelines for external service usage. This plugin may collect and transmit data to external services for security analysis:
Google Safe Browsing API: When URL reputation checking is enabled, URLs found in your content, posts, comments, and uploaded files are sent to Google’s Safe Browsing service to check against databases of malicious websites, phishing sites, and malware distribution points. This helps protect your site from security threats.
Data sent to Google includes: 
– URLs extracted from posts, pages, comments, and file content 
– Website URLs being analyzed for reputation 
– No personal information, user data, or site content is transmitted beyond the URLs themselves
Data NOT sent to Google: 
– User personal information or login credentials 
– Post content, comment text, or page content 
– Database information or configuration details 
– User behavior or analytics data
Your Privacy Rights: 
– In the current version (1.0.0), Google Safe Browsing integration is enabled by default for security protection 
– Future plugin updates will include user settings to disable external service usage 
– No data is collected or stored by VMP Fence itself beyond standard WordPress security logs
Third-Party Privacy Policies: 
– Google Safe Browsing API: https://developers.google.com/safe-browsing/v4/usage-limits 
– Google Privacy Policy: https://policies.google.com/privacy
Data Retention: 
VMP Fence caches URL reputation results locally for up to 1 hour to improve performance and reduce external API calls. These cached results are stored only on your server and are automatically purged.
Current Limitation: 
In version 1.0.0, Google Safe Browsing integration is automatically enabled for URL scanning. Future versions will include user settings to control external service usage. If you prefer not to use external services, please contact the plugin developer or wait for the next update which will include privacy controls.
<h3>GitHub WordPress Repository (File Comparison/Diff Viewer)</h3>
Service Purpose: 
VMP Fence connects to GitHub’s raw content service to download original WordPress core files for displaying file differences/comparisons in the admin interface.
Service URLs: 
– Primary: https://raw.githubusercontent.com/WordPress/ 
– Fallback: https://core.svn.wordpress.org/
When This Service Is Called: 
– Only when user clicks “View Differences” button on a scan result 
– Used to show side-by-side comparison of current file vs original WordPress core file 
– NOT called during regular scanning operations or automated processes
Data Sent to GitHub: 
– WordPress version number (e.g., “6.8”) 
– File path relative to WordPress root (e.g., “wp-admin/index.php”) 
– HTTP User-Agent header: “VMPFence Security Scanner” 
– NO personal data, user information, site content, or configuration details are sent
Data Received from GitHub: 
– Original WordPress core file content for comparison and repair 
– Public repository data only (no tracking or analytics)
Privacy Implications: 
– GitHub may log standard web server access logs (IP address, user agent, timestamp) 
– No authentication required – all accessed files are public WordPress core files 
– No data is collected or stored by VMP Fence beyond the file content used for verification
Required: 
– Optional feature – viewing file differences can be skipped 
– Internet connection required only when viewing file comparisons 
– Regular security scanning does not require this service
Third-Party Privacy Policy: 
– GitHub Privacy Statement: https://docs.github.com/en/site-policy/privacy-policies/github-privacy-statement
User Control: 
– This feature is only activated when user manually clicks “View Differences” button 
– No automatic background requests are made 
– Users can review scan results without using this feature

VMP Fence Security

Advanced WordPress security plugin with comprehensive malware scanner, vulnerability detection, and multi-layer protection system.

Sami Ahmed Siddiqui

This plugin helps safeguard your website against two common types of Cross-Site Scripting (XSS) vulnerabilities:
<ul>
<li>Reflected XSS: This happens when harmful scripts are hidden in a website’s URL. If a user clicks a link with such a script, it can run in their browser, potentially stealing their data or taking control of their system.</li>
<li>Self-XSS: This occurs when a user’s own input on your website is displayed back to them in an unsafe way, allowing malicious scripts to run in their browser.</li>
</ul>
This plugin provides several layers of protection:
Blocking: When active, the plugin checks URLs for specific characters. If it finds any of these characters in the URL, it redirects the user to prevent a potential XSS attack. You can customize which characters to block or allow.
<ul>
<li>Opening Round Bracket <code>(</code></li>
<li>Closing Round Bracket <code>)</code></li>
<li>Less than Sign <code><</code></li>
<li>Greater than Sign <code>></code></li>
<li>Opening Square Bracket <code>[</code></li>
<li>Closing Square Bracket <code>]</code></li>
<li>Opening Curly Bracket <code>{</code></li>
<li>Pipe or Vertical Bar <code>|</code></li>
<li>Closing Curly Bracket <code>}</code></li>
</ul>
Encoding: For an extra layer of security, the plugin encodes certain characters found in URL parameters. This stops harmful code from running, even if it’s present in the URL. You can also choose to exclude specific parameters from being encoded.
<ul>
<li>Exclamation Mark <code>!</code></li>
<li>Double Quotation <code>"</code></li>
<li>Single Quotation <code>'</code></li>
<li>Opening Round Bracket <code>(</code></li>
<li>Closing Round Bracket <code>)</code></li>
<li>Asterisk Sign <code>*</code></li>
<li>Less than Sign <code><</code></li>
<li>Greater than Sign <code>></code></li>
<li>Grave Accent “`</li>
<li>Cap Sign <code>^</code></li>
<li>Opening Square Bracket <code>[</code></li>
<li>Closing Square Bracket <code>]</code></li>
<li>Opening Curly Bracket <code>{</code></li>
<li>Pipe or Vertical Bar <code>|</code></li>
<li>Closing Curly Bracket <code>}</code></li>
</ul>
Escaping HTML in <code>$_GET</code>: This plugin automatically makes HTML characters safe within the <code>$_GET</code> variable. This is vital if your website pulls data from URLs and displays it as part of your web page. It helps prevent malicious scripts from being injected through user-provided input.
<h3>Important Notes:</h3>
<ul>
<li>After activating the plugin, thoroughly test your website forms, especially if you use WooCommerce. Make sure the plugin doesn’t interfere with your shopping cart and checkout processes.</li>
<li>We welcome bug reports for this plugin on GitHub: <a href="https://github.com/samiahmedsiddiqui/prevent-xss-vulnerability/issues" rel="nofollow ugc">https://github.com/samiahmedsiddiqui/prevent-xss-vulnerability/issues</a>. Please remember that GitHub is for bug reports only, not general support.</li>
</ul>
By using this plugin and following these recommendations, you can significantly improve your website’s defense against XSS attacks.
