What It Does

This plugin helps safeguard your website against two common types of Cross-Site Scripting (XSS) vulnerabilities.

Reflected XSS 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.

Self-XSS 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.

This plugin provides several layers of protection.

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.

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.

This plugin automatically makes HTML characters safe within the $_GET 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.

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.

By using this plugin and following these recommendations, you can significantly improve your website's defense against XSS attacks.
