XSS Attacks: How to Protect Your WordPress Website - ManageWP

There are over 27 million live WordPress websites. While it’s awesome to be part of such a large, active community, the Content Management System’s (CMS) popularity also makes it a prime target for Cross-Site Scripting (XSS) attacks.

Fortunately, just because hackers focus on WordPress doesn’t mean their breach attempts are destined to succeed. By using the right tools and techniques, you can harden your site against XSS attacks.

In this post, we’ll discuss what XSS is and why WordPress is uniquely vulnerable to these kinds of intrusions. Then we’ll share four strategies that you can implement to help protect your site against them. Let’s get started!

An introduction to XSS attacks

An XSS attack occurs when a hacker exploits a vulnerability on your website and attempts to inject unauthorized JavaScript code. The malicious script is then executed on either the client-side in the browser, or is stored and carried out on the server.

XSS attacks are often designed to collect data from your visitors, such as their passwords or payment information. However, the attacks can also change how your site looks or functions. For example, cybercriminals might redirect your users to an entirely different website.

This kind of redirect may result in your traffic plummeting, as the hacker steals 100 percent of your visitors. The rerouting can also be a launchpad to further attacks. For example, a nefarious redirect may send your traffic to a scammy website.

Some bad actors may even mimic your site, in an attempt to trick your customers into sharing personal information and payment details. This can be particularly disastrous for your reputation.

XSS attacks are a huge problem for many different CMSs. However, WordPress is uniquely vulnerable because many websites on the platform use plugins. These extensions add code to your site, which may introduce XSS vulnerabilities that hackers can exploit. In its 2021 report, WP White Security discovered almost 4,000 known WordPress plugin vulnerabilities, including ones that could result in successful XSS attacks.

With so many loopholes to exploit, it’s perhaps not surprising that Wordfence identified 330 million attempted XSS attacks in 2020. With cybercriminals actively trying to leverage known and unknown weaknesses, it’s important to do everything you can to protect your website.
