What you can do about plugin vulnerabilities

Despite being the most popular content management system to date, WordPress is still vulnerable to security breaches. In fact, we have mentioned before that there are nearly 4,000 known WordPress vulnerabilities in existence, threatening to destroy the hard work you have put into your website.

There are many entry points that can compromise your website and all of its data. For example, hackers can sneak in through your themes, via password theft, with brute force attacks, and even using old files.

And, with 61.5% of WordPress users admitting they don’t know how attackers get into their website, this should call for more education about website vulnerabilities.

More specifically, we should focus on the one thing that makes your website the most vulnerable – plugins.

Today we are going to look at how and why hackers might try to break into your website, and what you can do to prevent this from happening, so that you don’t become a victim to a plugin exploit and risk losing everything you worked so hard to achieve.

Why do hackers want into your WordPress website?

To start, it is important to understand that despite your best efforts to keep your WordPress website safe, plugins expose your website to a variety of security breaches.

This is because, although the WordPress core is safe and secure, plugins come from all over the place, are developed by tons of different people with different skill levels and standards, and quite frankly, are wildcards that you simply throw into your website.

And, if you are not careful, these wildcards have the potential to do a lot of damage.

As you can see, there are several ways a hacker can break into your website, especially using your site’s plugins. However, there are several ways you can prevent plugin vulnerabilities (and security breaches) on your website.

How to address plugin vulnerabilities on your WordPress website

2. WPSCan vulnerability database

If you notice a plugin that you use is on the list, make sure there is no update resolving the vulnerability before taking action.

If no solution has been applied, you might want to delete that plugin from your website and find an alternative that doesn’t open your site up to hackers.

Final thoughts

Plugins are great, don’t get me wrong. In fact, plugins are one of the main reasons the WordPress CMS is so popular. They extend the functionality and design of your website, oftentimes for free, and add a lot of value to your site visitors as they engage in your content.

However, failing to recognize the threat some plugins pose can do a lot of harm to your website. That’s why it is critical you conduct research before placing random plugins on your site, use reliable sources, and regularly monitor not only your website for changes that may lead to a breach in security, but other databases that will alert you to possible plugin vulnerabilities.

And, if you really want to make things easier, entrust ManageWP to manage and maintain your website, as well as keep it secure with advanced vulnerability scans.

Using the Orion Vulnerability Update feature, you can rest assured that your website is secure at all times. And, in the off chance it becomes vulnerable to attack, you can guarantee ManageWP will alert you immediately so that you can take the best measures to resolve the vulnerability and re-secure your website.
