Top 5 Most Common WordPress Vulnerabilities

Most Common WordPress Vulnerabilities

WordPress started as nothing more than a simple blogging platform where people could share their thoughts and, well, blog their way on the web.
However, nowadays WordPress is the main answer for any online problem/business – online stores, eCommerce platforms, news, application development, and even business marketing solutions.

WordPress has it all!

On the other hand, the entity is also an open-source platform. This means that any user can actively contribute to the development of WordPress’ core features and functionalities. The platform being open-sourced is also the main reason why we see so many creative WordPress themes out there – because people can freely create within the platform!

Naturally, the fact that it is so open makes this number one blogging solution prone to security vulnerabilities. As such, today’s article will explore five of the most common vulnerabilities that you may encounter while using WordPress.

Brute Force Attack

A brute force attack implies a trial and error procedure through which a written code uses thousands of combinations in order to guess an account’s username and password.

Even though this type of vulnerability is quite difficult to attack, it is still one of the most common ones. The main reason is the fact that WordPress doesn’t come with a limit on how many times you can try to authenticate and fail.

File Inclusion Exploits

When it comes to file inclusion exploits, vulnerable code is used in order to load certain remote files that would allow the attacker to easily gain access to your website.

This type of vulnerability is also the easiest way through which a hacker can access the wp-config.php file of your WordPress site – which is basically the very core of your website and can be used to change every single thing on it.


Believe it or not, scripts, outdated plugins, and even themes can be used to inject malicious code into the WordPress platform.

When someone does this, the code they inject an extract of data from your website while also inserting various malicious content in it. Such content is quite hard to spot as it is designed to be very discreet. 

In most cases, if your website is seriously damaged, then the whole WordPress site has to be reinstalled and hosting renewed. This is why it is very important that you use WordPress themes from reputable websites and sources!

SQL Injections

Any website based on WordPress uses a MySQL database in order to operate. When performing a SQL injection, an attacker can access the entire database of your website, as well as all of the data that’s on it.

On certain occasions, they can also rely on SQL injections to put new content or data into your database – obviously, links to spam or malicious websites are the most common type of inserted data.

DDOS Attack

If you’ve been online for quite some time, then you know the terror that comes with a DDOS attack. Anything that runs on a server and anyone that browses the internet can be a victim of such an attack.

Known as Distributed Denial of Service, DDOS implies a very large volume of requests that are made towards a web server. Naturally, the server usually can’t handle so many requests, slows down and, ultimately, crashes.

Operations can be slowed down to the point that users can no longer use websites/services properly. If the DDOS attack is serious, then the platform/service affected can get back on track after weeks and months of mitigation.

With a little bit of research, you can come across various businesses and live services that had to shut down completely due to such attacks.

The Bottom Line

Before considering a switch from WordPress to another platform, keep in mind that every single web service out there has its vulnerabilities. Switching them won’t help you that much.
Instead, you can learn how to protect yourself from such vulnerabilities – for example, you have to make sure that you always update your website, its plugins, themes, and so on.

The trick is not to avoid such vulnerabilities but to learn how to block the entries that attackers can use to hurt your website!
