A recent WordPress plugin supply chain incident is a good reminder of something we have believed for a long time at MantyWeb: your WordPress site should use the smallest number of trustworthy plugins possible.
That does not mean WordPress is a bad platform. One of its biggest strengths is its large plugin ecosystem and the flexibility that provides. You can build almost anything with it. But that flexibility only works well when it is managed carefully. As we wrote in Why Most Sites Are a Good Fit for WordPress, WordPress is powerful, but that power comes with real maintenance responsibilities.
Every plugin you install is another piece of third-party code running inside your WordPress environment, often with the ability to affect your site’s data, admin workflows, or visitors’ experience. That is not automatically a bad thing. It is just something site owners need to take seriously.
What Happened
Recently, WordPress.org warned users that several plugins from the author “essentialplugin” contained code that could allow unauthorized third-party access. According to the warning, the plugins downloaded code from analytics. essentialplugin. com, installed a backdoor file designed to resemble a core WordPress file, and were used at least to inject hidden spam links, redirects, or pages into affected sites through wp-config.php. You can read the WordPress.org warning here.
WordPress.org also warned that its automatic cleanup may not have removed everything. A forensic write-up from Anchor Hosting found that the forced update neutralized the phone-home behavior, but did not remove malicious code that had already been injected into wp-config.php. You can read that write-up here.
The Real Problem Is Plugin Selection
The broader lesson, in our view, is not just about old plugins or missed updates. It is also about how plugin stacks get built in the first place.
A lot of WordPress sites end up with a collection of sliders, popups, galleries, SEO add-ons, form helpers, and assorted utilities that were each installed because they seemed useful at the time. But each additional plugin can increase your attack surface, raise the odds of conflicts, add update risk, and make it harder to diagnose problems when something goes wrong.
That is one reason we recommend keeping plugin stacks lean. Our WordPress audit guide makes this point directly. Plugin stacks tend to get bloated over time, and one of the most valuable things you can do is reduce overlap, remove inactive plugins, and replace anything untrusted or poorly maintained.
What a Better Plugin Stack Looks Like
The goal is to simplify. Use fewer plugins, and make sure each one earns its place.
Take SEO as an example. You do not need three SEO plugins, two schema plugins, and a metadata helper all doing overlapping work. In most cases, one solid option is enough.
Yoast SEO is a good example of the kind of signal we look for in an important plugin. Its WordPress.org page shows a massive installed base, an active update history, and a strong public support and review footprint. That does not make it risk-free. No plugin is. But it is a very different risk profile from a plugin with a thin update history, unclear ownership, and little public support activity.
The same logic applies across your whole stack. Use one good form plugin, not three. Use one backup system, not two that overlap. Be skeptical of “nice to have” plugins for sliders, widgets, or cosmetic effects if they are not clearly helping the business.
If a feature is not mission critical, it should have a high bar to earn a place in your stack.
A Simple Audit Process
Start with a plugin audit. Go through everything installed on the site and ask four questions:
What does this plugin do? Is it still needed? Is it actively maintained by a trustworthy vendor? Is another plugin already doing the same job?
That process alone usually surfaces at least a few plugins that should be removed, consolidated, or replaced. Our How To Audit Your WordPress Website guide and our How to Perform a WordPress Security Audit article are both good places to start if you want a structured checklist.
As our Complete WordPress Maintenance Guide for 2025 puts it, you should keep your plugin library lean and trustworthy, remove unused plugins, and treat vulnerability warnings as urgent rather than optional.
