WordPress Is Not Dangerous — Poor Plugin Management Is

Recently, when looking at WordPress-related news, I think many people are starting to get the impression that “WordPress is dangerous.”

However, in reality, the main issue is not WordPress core itself so much as plugin vulnerabilities.

In fact, according to a WordPress vulnerability report dated April 1, 2026, 225 vulnerabilities were disclosed in just one week, and most of them were related to plugins and themes. Furthermore, 91 of them were still unpatched at that time, making operational response speed more important than ever.

In this article, I will explain from a practical perspective why plugins so often become the biggest risk in WordPress, and what realistic countermeasures site owners can take.

Conclusion: WordPress Itself Is Not the Danger — Plugin Management Is

To start with the conclusion, WordPress itself is not the danger. Plugin management is.

WordPress core is updated continuously, and security fixes are generally clear and well maintained. In fact, even in recent vulnerability reports, the focus of attention has been overwhelmingly on plugin-side issues, not WordPress core.

In other words, the security of a WordPress site changes significantly depending on which plugins you install and how you manage them.

Why Plugins Tend to Be Risky

1. Quality Varies Widely

WordPress plugins are extremely convenient, but their development systems and quality levels vary greatly. Some are maintained continuously by large companies, while others are run in a way that is much closer to individual development.

As a result, even among equally “useful plugins,” the reality is that there can be a very large gap in security maturity.

2. Maintenance Can Stop

On WordPress sites, plugins are often kept in use for a long time once installed. However, due to changes in the developer’s circumstances or business direction, update frequency may drop, or the plugin may effectively be abandoned.

If a new vulnerability is discovered in that state, it becomes very easy to keep using it without a fix, which is highly dangerous.

3. The Time from Disclosure to Attack Is Short

These days, the time between a vulnerability being disclosed and it being actively attacked has become quite short. Some reports indicate that exploitation begins almost immediately after disclosure, which makes it much harder to say, as in the past, “We can update when we have time.”

4. Plugin Combinations Easily Become Complex

The strength of WordPress is its extensibility, but as you keep adding features, the number of plugins naturally increases.

That often leads to issues such as unused plugins being left behind, overlapping plugins serving similar purposes, and losing track of why certain plugins were installed in the first place.

In that state, not only do vulnerabilities themselves become a problem, but the difficulty of managing everything also becomes a risk.

The Reality of 2026

Looking at recent reports, plugin vulnerabilities are by no means rare or exceptional cases.

For example, in the report dated April 1, 2026, 225 vulnerabilities were disclosed in one week, of which 203 were plugins and 22 were themes. Moreover, 91 remained unpatched.

Recent news has also highlighted major cases, such as many sites remaining unupdated in response to a Smart Slider 3 vulnerability, and the update infrastructure of BuddyBoss being compromised.

In other words, in modern WordPress operations, it is extremely important not only to ask “Does a vulnerability exist?” but also “Is my site in a state where I can notice and respond to it?”

Site Conditions That Are Especially Dangerous

From a practical standpoint, the following conditions are quite risky.

• Unused plugins are still installed
• Update notifications are seen but postponed
• There are plugins whose origin or purpose is unknown
• The site is being operated without backups
• Updates are applied directly to the production site without testing

These situations do not necessarily come from bad intentions. In many cases, they simply happen when people are busy running a site as usual.

That is exactly why WordPress security issues are not just technical problems, but also operational problems.

Is “Just Update Everything” Really Enough?

This is an important point.

Of course, updating is extremely important. If a vulnerability has been fixed, then the update should be applied as quickly as possible.

However, in real-world work, “just updating everything” does not solve the whole problem.

The reason is that on WordPress sites, plugin updates can sometimes cause layout issues or functional failures. This is especially common on sites where multiple plugins interact in complex ways, or where many customizations have been added.

So in reality, there is a somewhat troublesome situation where:

• Not updating is dangerous
• But updating can also break things

That is why what is truly needed is an operational process that allows updates to be applied safely.

Realistic Countermeasures for Safe Operation

1. Reduce the Number of Plugins

One of the most effective measures is simply not to install too many plugins.

More features make a site more convenient, but they also increase the attack surface. It is safer to remove unnecessary plugins, plugins whose role is already finished, and plugins that can be replaced by other solutions.

2. Choose Trustworthy Plugins

When introducing a plugin, it is important to check things such as update frequency, number of users, the developer behind it, and the support situation, and confirm whether it is being maintained continuously.

It is not enough to think, “It looks useful, so let’s install it.” You also need the perspective of whether it can be used safely over the long term.

3. Update Regularly

Since the time between vulnerability disclosure and attack is getting shorter, postponing updates is becoming increasingly dangerous.

Ideally, updates should be built into regular operational work. Rather than reacting only when someone happens to notice, it is much more stable to decide on a cycle for checking and updating.

4. Always Take Backups

You should avoid being in a situation where no backup exists before an update. If you can restore the site immediately when something goes wrong, the psychological barrier to updating becomes much lower.

5. Prepare a Test Environment If Possible

Rather than updating directly on the production site, it is much safer to test first in a staging or cloned environment.

This is especially valuable for sites with important functions such as booking systems, membership features, payments, or forms, where pre-update testing has particularly high value.

The Operational Policy I Recommend in Practice

What I consider important in practice is not so much “building a site with no vulnerabilities”, but rather “building a site that can respond calmly when vulnerabilities appear”.

More specifically, the following policy is realistic.

Even if only this level of operation is in place, a site’s ability to respond when vulnerability news appears changes dramatically.

One Thing I’ve Felt in Practice: Simply Following the Information Changes the Initial Response

In this recent case, one of my clients was using Smart Slider 3, so after the plugin update was released, I contacted them and advised them to apply the fix as quickly as possible.

Of course, it is not easy to keep a complete grasp of every single plugin installed on every client site. Depending on the site, there may still be plugins left behind by a previous agency or past administrator.

Even so, simply keeping an eye on security reports for major plugins and recent vulnerability news can make a major difference in initial response.

At the very least, it helps avoid the situation of “dangerous information comes out, and the site is left untouched simply because nobody noticed”. It also makes it easier to reach out when updates or checks are needed.

When it comes to WordPress security, I feel that the key is not some special trick, but rather the steady accumulation of learning about new information early and carrying out the necessary responses one by one.

Maintenance Contracts as an Option

That said, in real-world operations, it is not easy to keep tracking plugin updates and vulnerability information while also handling everyday business.

In particular, situations like the following often lead to delay:

• Not knowing which plugins are truly necessary
• Not being sure whether an update is safe to apply
• Being afraid that updates will cause problems
• Finding it hard to judge whether vulnerability news actually affects your own site

In those situations, things tend to be pushed to the back burner.

That is why, for stable WordPress operation, it is reassuring to have a maintenance structure that includes regular checks, updates, backups, and initial response when needed.

On my side as well, depending on the condition of the WordPress site, I provide ongoing support in forms such as:

• plugin audits and cleanup
• checking and handling updates
• maintenance operations that consider the risk of problems after updates
• improvement proposals with security in mind

So if you feel that “continuing to manage this site entirely on our own is starting to feel a bit risky” or “we would like to have someone we can rely on for updates and vulnerability response”, please feel free to get in touch about maintenance support.

Depending on the size of your site and your current operating situation, I can suggest a practical maintenance approach that does not put too much strain on your team.

Summary: The Biggest WordPress Challenge Is Not Development, but Management

When people look at WordPress vulnerability issues, it is easy to jump to the overly broad conclusion that “WordPress is dangerous.”

But in reality, the situation is not that simple.

The real issues lie in day-to-day management: plugin selection, updates, cleanup, and testing.

Put another way, if you handle those things properly, WordPress is still a highly practical and powerful CMS.

If your current site is in a state where “we are not even sure which plugins are truly necessary”, “updates have stopped because we are afraid of breaking something”, or “every vulnerability headline makes us uneasy”, then there is a lot of value in reviewing your plugin inventory and operational design.

WordPress security depends less on special tricks and more on steady, sustainable management. A good place to start is by reducing unnecessary plugins, taking backups before updates without fail, and building an operational structure that is realistic for your situation.
