WordPress Security Issues & Vulnerabilities You Should Know About it

WordPress Security Issues

WordPress Security Issues- “Security impacts everybody equally. There’s nobody specific topic, target, or audience once it involves web site security,” Victor Santoyo aforementioned throughout his session ”Security lessons learned from 2021” at WordCamp Europe 2022. 


But WordPress is the most well-liked CMS on the web. It’s conjointly the foremost hacked. for instance, in 2020, Wordfence according to over two,800 attacks per second targeted WordPress.


Cyber attaks


Cyber attacks waste time, energy, and money. and that they may also threaten your authority and name, particularly if your website guests square measure full of the attacks. whereas it’s not possible to quantify the amount of day-after-day threats your website might face, it’s essential to acknowledge and perceive WordPress-specific problems do you have to fall victim to at least one of them.


This article can reassess a number of the foremost common WordPress security and vulnerability problems, why they have an effect on WordPress sites, and also the steps you’ll be able to fancy to make sure you aren’t affected. 

obsolete Core software system


An advantage of employing a {website|web website} building platform instead of building a site from scratch is that developers can ceaselessly enhance the practicality and security of the platform to produce seamless user expertise.


WordPress developers roll out updates every 3 months. It’s powerfully suggested that every WordPress users transfer these updates after they become accessible either manually or by enabling auto-updates. every one of those releases usually embodies enhancements, bug fixes, and fixes to additional important security vulnerabilities. therefore changing your core files will facilitate improving your site’s practicality, performance, and compatibility additionally to security.


Despite the auto-update feature, Santoyo aforementioned that, in line with Sucuri’s info, “50.3% of infected WordPress websites were obsolete.”


This share will look higher than the opposite CMSes like PrestaShop, vBulletin, and Typo3, which had 100 percent of infected websites running on the obsolete software system. “[But] it is important to notice that fifty of WordPress is additional websites than the 100 percent of Typo3 and alternative platforms. therefore there is still a big portion of WordPress websites running on obsolete software systems,

Why square measure WordPress sites vulnerable?


Outdated core WP software system leaves sites vulnerable as a result of updates square measure sometimes designed to deal with important security problems. Users WHO don’t transfer associate degree update square measure then at risk of hackers. for instance,  WordPress version five.8.1 enclosed fixes for 3 major vulnerabilities, together with a cross-site scripting (XSS) vulnerability within the Gutenberg block editor.


If your software system is obsolete, you’re conjointly unable to update your themes and plugins (which we’ll cowl below), and your website becomes additional at risk of several of the protection threats on this list.


What you’ll be able to Do


WordPress offers automatic updates for every restructure of WordPress. you’ll be able to flip those on in your dashboard to make sure your core files stay up-to-date. If you don’t, then you’re effort your website at risk of illustrious threats yet as illustrious threats.

obsolete Themes and Plugins


One of the most important appeals of WordPress is its customizability. Developers produce many distinctive themes and plugins that WordPress website homeowners will use to customize their sites. 


However, these extensions need website homeowners to require correct security precautions. As mentioned higher than, a superannuated core software system will expose your website to security risks, then will obsolete themes and plugins. 


 In fact, in line with knowledge from WPScan, more or less ninety-seven vulnerabilities in their info square measure plugins and themes and solely four-dimensional square measure core software system.


Sucuri Security saw similar leads to its info. “In 2021, vulnerable plugins and extensions accounted for a lot of additional compromises than merely having the obsolete core on your website,” Santoyo aforementioned throughout his WCEU 2022 session.


Why square measure WordPress Sites vulnerable?


Theme and plugin developers usually unleash updates with practicality enhancements and extra security measures. However, not all developers do. 


When they don’t try this, sites exploitation these resources become at risk of hackers WHO will use obsolete tools as entry points. for instance, say WordPress has a free associate degree update with a brand new security patch however a developer hasn’t updated their theme to be compatible with new needs. therein case, a hacker may exploit the theme’s vulnerability and gain management of a website. 


In addition, if developers do unleash updates, website homeowners WHO fail to put in them will build their sites additionally vulnerable. 


What you’ll be able to Do


“Whoever is full management of an internet site ought to perpetually ensure its inventory of software system is up to this point,” Santoyo stressed throughout his WCEU session. 


Updates serve to enhance WordPress theme security and can defend your website. once updates are square measure accessible for plugins and themes, you’ll be able to install them manually or use a plugin to mechanically install them as they are going live.



Malware may be a broad term that features any malicious software system (hence, “mal-ware”). Hackers will place malware files in legitimate website files or plant code in existing files to steal from websites and their guests. The malware may conjointly try associate degree unauthorized login via “backdoor” files or play general disturbance.


In 2021, 61.65% of remediated websites within the Sucuri info were infected with malware. In 2019, 39.53% were, in line with Santoyo.

Why square measure WordPress Sites vulnerable?


Like several of the problems on this list, being vulnerable to malware is directly associated with alternative problems. for instance, malware sometimes enters WordPress sites through unauthorized and obsolete themes and plugins.


Hackers benefit from security issues in plugins and themes, imitate existing ones, or maybe produce entirely new add-ons for the only real purpose of putting harmful code on your website. 


For example, the AnonymousFox hack was the foremost standard kind of malware infection in 2021. “It continues to be a significant threat to WordPress sites designed on cPanel,” Santoyo aforementioned throughout his presentation at WCEU. With this hacking tools suite, they get access to your admin panel and install malicious plugins at intervals in your file structure, among alternative real plugin files. this is often effective as a result of “if not invariably wanting at intervals your file directory, you wouldn’t see it,” Santoyo aforementioned.


What You Could Do


WordPress restricts the file types that users can upload to the media library by default. If you attempt to upload a file that is not included, you will receive an error message and your file will not be uploaded. Of course, as the administrator, there are ways around this, but this is one step WordPress takes to prevent malware.


Aside from that, here’s what you can do: First, thoroughly test each plugin and theme that you install on your WordPress site. WordPress.com provides useful statistics for all plugins in their directory, as shown in the example below:


You should also run regular security scans on your WordPress website to detect any potential malware. “The most important solution is visibility,” Santoyo said. “That is why monitoring detection can be useful: it will tell you exactly what file changes have occurred in the last few days.”


Plugins are your friend here: there are many powerful security plugins available that can scan for malware and repair damaged files. Defender by WPMU DEV, for example, has malware scanning and other features to prevent many of the other issues on this list. You can also look through our list of recommended WP security scanners for more options.


Why are WordPress sites at risk?


WordPress accounts for the majority of skimmer infections by CMS, accounting for 34.5 percent in 2021. “Last year, WordPress surpassed Magento, a major e-commerce CMS, in terms of the number of credit card skimmers detected,” he said.

WooCommerce is the most popular e-commerce platform for the top 1 million sites, according to Builtwith data. “Attackers want the highest ROI possible on attacks like this,” Santoyo explained. As a result, it’s not surprising that credit card skimmer attackers have shifted their focus to the most popular eCommerce platform on the internet.


Credit card skimmers, like the other security issues on this list, take advantage of vulnerable software, weak passwords, and other points of entry. Once they have gained access to your admin areas, attackers will inject a malicious payload among a website’s plugins, themes, or other legitimate files and obfuscate it in order to collect as many credit card details as possible from your site.


What You Could Do


“Attackers benefit financially more from credit card skimmers than from other types of infections.” “As it becomes more profitable for these attackers, exploit kits will likely become 

more complex and sophisticated,” Santoyo said. As a result, he believes that DIY cleanups will become more difficult.

His recommended solution is a monitoring tool like Sucuri SiteCheck, which scans your website for known malicious content and malware injections and shows you what attackers want with your information.

Unspecified User Roles


When you create a WordPress site, you can select from six different user roles, such as Subscriber or Administrator. Each role includes native permissions that enable or disable users from performing specific actions on your site, such as modifying plugins and posting content. The Administrator user role is the default, and it has the most control over any given WordPress site.


Why are WordPress sites at risk?


If you have multiple users and do not change the default settings, everyone becomes an admin, which can be problematic. This does not necessarily imply that the people with whom you are collaborating will cause you harm, but it does imply that a hacker who gains access to your site will be able to make changes as an administrator.

If brute-force attacks are successful, poorly defined admin roles expose your site to increased risk, as admin roles can give a hacker complete control over your site. Furthermore, cross-site scripting (discussed below) grants hackers access to front-end capabilities, allowing them to obtain additional information from your site visitors.


What You Could Do


Monitor all permissions on your WordPress site, regardless of its purpose. If you’re the only admin on your site, make sure you’ve added extra security measures to keep hackers out, such as two-factor authentication or longer passwords. When assigning roles to others, make sure you only give them the permissions they need. Because mistakes can occur, you should also ensure that a contributor does not delete a high-performing post by accident.

Spam from Search Engine Optimization (SEO)


These spammy hacks are similar to SQL injections, but they target the most important aspect of any website owner’s business: SEO. These hackers take advantage of your high-ranking pages, filling them with spammy keywords and pop-up ads, and then selling items or counterfeit merchandise using your hard work.


Why are WordPress sites at risk?


WordPress sites are vulnerable to these attacks in the same way that outdated plugins, themes, and the core software are. Successful brute force attacks and undefined user roles can also expose your site.


These hacks are also more difficult to detect, making them even more dangerous. Hackers will frequently gain access but delay making any changes in order to avoid raising immediate suspicion. Because they are SEO-based, these spammy keyword additions are only placed on your high-ranking pages, so they will go undetected during a site-wide review. The hackers simply insert a keyword here and there within relevant pages, such as “cheap Chanel bags,” leaving your code relatively intact.


This means that SEO spam is most visible to SEO crawlers because they will index your site for spammy keywords and users searching for Chanel bags (or whatever the spammy keyword is).


What You Could Do for WordPress Security Issues


One of the first things you can do is implement the previously mentioned security measures, such as timely updates and user roles. You can also run malware scans with a WordPress security plugin. We’ve compiled a list of high-quality security plugins as well as a security checklist to help you protect your website from SEO spam (and other issues on this list).


If you want to find these hacks on your own, pay close attention to your analytics data and note any unexpected changes in SERP positions or increased site traffic. You may also be notified by an internet browser if your site appears in search results for something that does not appear to be related.
