Informations about the package prevent-xss-vulnerability
Prevent XSS Vulnerability
This plugin helps protect your website from two common types of Cross-Site Scripting (XSS) vulnerabilities:
- 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.
- 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.
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.

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.

Escaping HTML in $_GET: 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.
