How To Prevent Cross-Site Scripting In WordPress

WordPress is one of the most popular site-building and content management systems today. Unfortunately, its popularity also makes it a prime target for hackers. One of the most common attacks on WordPress sites is known as cross-site scripting or XSS. Unfortunately simply knowing what XSS is doesn’t help to prevent it, so the question remains: “How to prevent cross-site scripting in WordPress?“. Thankfully we have a few solutions to fight this attack.

What is XSS?

XSS, or cross-site scripting, is a type of computer security vulnerability that allows attackers to inject malicious code into webpages viewed by other users. By exploiting XSS vulnerabilities, attackers can execute malicious scripts in the victim’s browser which can hijack user sessions, deface websites, or redirect users to malicious websites.

XSS attacks are a common method of attack used by hackers to exploit vulnerabilities in web-based applications. In order to protect against XSS attacks, developers need to design and code their applications in a way that prevents untrusted input from being executed as code.

There are three main types of XSS attacks: reflective, persistent, and DOM-based. Reflective XSS attacks occur when an attacker injects malicious code into a web page and the code is reflected back to the user’s browser.

How does WordPress make you vulnerable to XSS?

In order to prevent cross-site scripting in WordPress, it is crucial to take some preventative measures. This includes ensuring that your plugins and themes are up to date, as well as using a security plugin. Additionally, you should avoid clicking on unknown links and be careful when sharing information on social media. By following these simple tips, you can help keep your WordPress site safe from potential attacks.

3 Ways to prevent XSS in WordPress

1. Use a WordPress Security Plugin

There are many great security plugins available for WordPress that can help to prevent XSS attacks. Some of our favorites include Wordfence, Sucuri, and iThemes Security.

2. Keep Your WordPress Site Updated

Another way to help prevent XSS attacks is by using strong passwords and two-factor authentication on your WordPress site. Doing so will make it much harder for attackers to gain access to your site.


In conclusion, following the steps above will help prevent cross-site scripting in WordPress. Be sure to keep up to date with the latest security releases and update as soon as possible. If you have any questions, reach out to a professional for help.
