It would be nice if WordPress sites weren’t vulnerable to hackers. Everything was safe and secure, right out of the box. Unfortunately, that’s not the case with WordPress, or any website.
Most safety issues aren’t because of WordPress core vulnerabilities. It’s usually because somebody didn’t implement simple preventative measures.
As you’ll see in this article, fixing vulnerabilities in WordPress is, for the most part, simple and easy to do. It just requires due diligence on your end and putting systems in place to ensure that hackers can’t access your site and make themselves at home.
Plus, with some plugins’ help, quite a few vulnerabilities are taken care of automatically—many of them with our security plugin, Defender. We’ll be recommending him and other plugins throughout this post.
This article will take a close look at:
- Why WordPress is Vulnerable
- Seven Common WordPress Security Vulnerabilities and Fixes
1. Outdated Plugins or Themes
2. Your WordPress Isn’t Upgraded to the Latest Version
3. Poor Hosting Environment
4. Giving Users Unnecessary Privileges
5. Weak Password
6. Using WordPress’s Default Login Area
7. Not Using SSL/HTTPS
With that being said, let’s look at why WordPress is vulnerable to hackers and also seven common WordPress security vulnerabilities — and how to fix them.
WordPress is by far the most popular website builder, which makes WordPress sites a frequent target of malicious attacks from hackers and bots, partially because of how many sites there are.
It’s also easier for hackers to locate WordPress vulnerabilities. And, well, that leads to frequent WordPress security issues.
The good news is WordPress doesn’t have to be vulnerable.
More common than not, WordPress vulnerability is due to admins neglecting simple tasks (e.g. keeping WordPress up to date and using strong passwords). When precautions are put in place, your site’s chances of staying safe are better.
You can do other things, such as having good hosting, removing outdated plugins, and more. We’ll get into all of the essentials in a moment.
Also, WordPress has you covered with their experts when it comes down to the core of things.
WordPress’s security team is made up of over 50 professionals. And to ensure issues are handled well, the team sometimes collaborates with other security pros to address problems in common dependencies.
In a nutshell, the sites that aren’t updated, well maintained, and don’t have security precautions implemented are the most vulnerable ones.
So, let’s take a look at the most common WordPress security vulnerabilities and how to fix them if these measures are not already implemented on your site.

Whatever the case may be, it’s best to try to prevent it from the start by limiting admin access.
A strong password is recommended almost always, whether for WordPress or any other online site. Yet, weak passwords are still common.
Hackers design bots that have the sole purpose of figuring out your login credentials. They try hundreds of usernames and passwords — all in just a few minutes. It’s known as a brute force attack.
When there are hundreds of login attempts on your site, it can take a toll on your server. This can slow down your WordPress site, and your site may crash due to a system overload.
We’ll break this up into two separate fixes.
First off, a strong password is an easy fix. You can change and create a password in the WordPress admin under Users > Profile.
WordPress will generate and recommend a strong password for you. Or, you can create your own.
WordPress’s recommended password has all you need for security, and it’s best to use it, or something similar if you create your own.
When it comes to brute force attacks, this can be stopped with our free security plugin, Defender, and his strong firewall.
Defender will lock out users after a failed number of login attempts.
You can change the threshold of how many login attempts are allowed before a lockout, the lockout duration and create a customized message to the user to let them know what happened.
The firewall also includes 404 Detection and IP Banning. Plus, if you really want to up your login game, Defender also has 2-factor authentication.

6. Let’s Encrypt for all of our SSL certificates. Plus, we offer free Wildcard SSL for Multisite subdomains.
