Most Common WordPress Security Issues & Vulnerabilities

Website owners and site owners are very concerned about WordPress security. Your secure online presence can only be maintained by understanding and fixing WordPress security flaws and vulnerabilities.

As a website owner, it’s critical to be aware of potential security issues and implement the necessary security measures to protect your website.

One of the most frequent security issues is the login page, which could be targeted by malicious individuals trying to gain unauthorized access using login information they got in various ways. Website security can be considerably improved using features like two-factor authentication and mandating strong password combinations.

To ensure that security fixes are implemented immediately, it’s also crucial to regularly update WordPress’ core, plugins, and themes. Site owners could consider integrating security plugins and altering the WordPress configuration file to reinforce security measures further.

Website owners can secure their websites against potential security flaws and create a robust website security architecture by using these best practices and utilizing WordPress’ built-in security capacities.

We’ll go through each issue along with a solution.

1. Outdated Software, Plugins, and Themes

It is crucial to make sure that WordPress is updated regularly. Unfortunately, you’re more susceptible to attacks if you’re one of the WordPress users using an out-of-date software version.

Outdated initiatives, plugins, and themes cause some of the most prevalent WordPress security issues. Developers of themes and plugins frequently provide updates that contain vital security patches and bug fixes.

Managing updates for any extensions you have placed on your website could help prevent attacks.

Recommended Fixes:

Every time you log into your site, you should ensure that all your software, plugins, and themes are updated.

By navigating to Dashboard Updates in your WordPress admin, you may check to see whether updates are available.

From the dropdown menu, choose All, then select Delete. You can navigate to Appearance Themes and remove any inactive WordPress themes there. The Delete button is in the bottom right corner. Click it after choosing the theme you would like to remove.

2. Brute Force Attack :

A brute Force Attack is a multiple-attempt method of determining the proper username and password. In simple words, it is equivalent to repeatedly beating on a door until it opens.

Despite being challenging, brute force attacks account for 16.1% of WordPress vulnerabilities.

Because WordPress allows users to make many tries, the Brute Force Attack is feasible. A persistent brute force attempt can overburden the server and degrade performance even if they cannot find your login information.

Recommended Fixes:

Making a strong password and username using capital letters, symbols, and

numbers is a quick and easy technique to resist brute-force attacks. Your website may be protected against the Brute Force Attack by using two-factor authentication (2FA) and bot prevention measures like captcha login. Try to keep the number of login attempts to a minimum.

The default WordPress login URL will make it harder to discover your login information. Thus, it’s best to modify it. However, you may forget the new URL and lose access to the website.

3. Weak Passwords

Using weak passwords is one of the significant errors that site administrators and users make. Hackers can more easily access your website if you choose passwords that are simple to guess.

For instance, To break the code and get access, agents and bots employ a variety of password combinations throughout this attack. To access your website, they make use of your login page.

Recommended Fixes:

This is why ensuring each user logs into your WordPress website using a strong password is essential. We advise using a password generation tool, such as the one included with WordPress user pages.

Additionally, changing your passwords regularly is a good idea. Using a password management program like NordPass or LastPass might ease your concerns about password loss.

Similarly, we recommend restricting login attempts and turning on two-factor authentication (2FA). These functions are not included by default in WordPress. However, adding them is simple if you use a WordPress login security plugin like Loginizer.

4. SQL Injection

Injecting SQL queries into any web form or input field is one of the first hacks in the web’s history that can change or destroy the database.

A hacker can alter the MySQL database after a successful attack, and they may even succeed in accessing your WordPress admin or modify the login information to cause further harm.

Usually, beginner to average hackers primarily testing their hacking skills carry out this kind of attack.

Recommended Fixes:

Using a plugin, you can tell if your website has experienced SQL Injection. You may check that with WPScan or Sucuri SiteCheck.

Update both WordPress and any themes or plugins that may create issues. To report such issues, they may create a fix, review their documentation, and visit their help forums.

5. Cross-Site Scripting (XSS) Attacks

Using Cross-Site Scripting (XSS) attacks, an attacker can insert harmful code into a website, which is subsequently executed by every user whose browser accesses the compromised page.

This can lead to the loss or unauthorized use of sensitive data, like login passwords or personal information, and it can also be used to launch additional attacks like phishing or the distribution of malware.

Recommended Fixes:

Use appropriate data validation across the WordPress site to prevent this attack. To ensure the correct data type is being added, use output sanitization. Additionally, plugins like Prevent XSS Vulnerability can be utilized.

It’s crucial to adhere to recommended practices like these to stop XSS attacks in WordPress:

•  Update plugins and themes, validate and sanitize user input, and

•  Maintain WordPress Core’s updates.

•  To monitor traffic and stop unauthorized users from accessing your system, use a Web Application Firewall (WAF).

6. Malware

Malware is a tool that hackers could use to infiltrate your website with malicious code and steal personal information. If you’re working with a hacked website, your files are likely contaminated with malware.

Malware comes in a variety of forms. Malicious redirection, drive-by downloads, and backdoor attacks are some of the most frequent types of harming WordPress websites.

The most effective strategy of action in dealing with these security vulnerabilities is prevention. But even with protective measures, malware can still affect you.

Recommended Fixes:

Verifying whether malware is there is the first step. It could exist in your database, files, or directories. To search for unwanted software on your website, utilize a WordPress malware scanner plugin. Wordfence is a well-liked plugin for this purpose.

An endpoint firewall and malware scanner are included in this freemium plugin to assist you in maintaining the security of your online applications. A 2FA function is also included.

There are several ways to remove malware from WordPress. Remove the damaged file or restore a prior site version from a backup, depending on how much your website has been impacted. This is only one of the critical benefits of routinely backing up your website.

7. HTTP Instead of HTTPS

Google has always emphasized the value of website security and how it affects SEO. Running your website through Hypertext Transfer Protocol (HTTP) instead of Hypertext Transfer Protocol Secure (HTTPS) might result in specific frequent WordPress security vulnerabilities.

If your site’s URL name in the browser bar has a closed padlock icon next to it, it is running over a secure connection.

Otherwise, visitors will see a red triangle icon and the statement “Your connection is not private.”

Recommended Fixes:

An SSL certificate is used when a website displays the padlock icon, a trust badge. The SSL protocol encrypts transmission from a website to a browser to prevent data from being intercepted or misused by a third party.

8. DDoS Attacks

DDoS attacks occur when an attacker uses infected networks or machines to transmit traffic to a single target.

The website may become inaccessible to visitors due to the server overloaded by the sheer traffic volume. A DDoS attack on a WordPress website can cause severe downtime, decreased performance, reduced revenue, and damage to reputation.

Recommended Fixes:

You must use secure WordPress hosting with top-notch security plugins to secure your website from malicious traffic and DDoS attacks.

•   Utilize a CDN to spread the strain of incoming traffic and defend against DDoS assaults by absorbing the bandwidth before it reaches your website.

•  You can protect your website from attacks like DDoS using one of the many available DDoS protection plugins for WordPress.

•  Ensure that the hosting company you choose has DDoS protection and that its servers can handle a lot of traffic.

9. Open Source Content Management System

Because it works as a content management system (CMS), WordPress is a popular option for website owners in various businesses because it makes publishing, organizing, and changing information simple. It’s crucial to be aware of any vulnerabilities when using WordPress.

The source and PHP codes used to create WordPress websites include one vulnerability. The code may include vulnerabilities that malicious actors try to use to access websites or sensitive data without authorization.

Strong security measures, such as employing secure login credentials and strong password combinations, must be implemented to reduce these risks.

Recommended Fixes:

Protecting against SQL injections is also crucial. These attacks target user input fields to modify database queries and obtain unauthorized access to private information.

Another essential step in keeping a secure WordPress environment is routinely upgrading and patching WordPress core, plugins, and themes. By actively detecting and thwarting possible attacks, security plugins can add a layer of defense.

Site owners should carefully examine the configuration file to ensure the proper security settings are in place. Site owners may safeguard user accounts, media assets, and the general security of their WordPress CMS by adopting these precautions and remaining attentive.
