The Hidden Security Risks of Updating WordPress

Skipping WordPress updates puts your business at risk. But here’s what most site owners don’t realize: updating incorrectly can be just as dangerous. Thousands of Hispanic business owners across the United States run WordPress sites that desperately need consistent maintenance, yet many either avoid updates entirely or handle them without a real strategy. The truth is, the security risks of updating WordPress go far deeper than most people understand.

This guide walks you through what can go wrong during an update, how to actually minimize those risks, and when it’s time to bring in a professional who knows what they’re doing.

Why WordPress Updates Are Essential—And Potentially Problematic

WordPress updates exist for one reason: to patch security vulnerabilities that hackers discover constantly. Here’s the catch—the update process itself can break your site if you’re not careful about it.

Every update closes security gaps, improves performance, and adds new features. The problem? Cybercriminals know exactly when those updates drop and which vulnerabilities they’re patching. If your site doesn’t update immediately, you’re essentially leaving the front door unlocked. But rush the update without preparation, and you risk destroying your site completely. Outdated plugins stop working, your theme becomes incompatible with the new WordPress version, or database changes trigger fatal errors that take your business offline.

The real issue is that most site owners treat updates like a binary choice: either ignore them entirely or just hit the button and hope for the best. Neither approach works. A thoughtfully planned update strategy is your actual defense.

The Real Security Risks When Updating WordPress

Plugin and Theme Incompatibility

One of the most common headaches after a WordPress update is plugins and themes breaking. Picture this: you update to WordPress 6.5, but your contact form plugin was built for older versions. Suddenly, forms don’t submit, your site looks broken, or you see the dreaded white screen of death.

This problem is preventable. Before updating, you need to verify that every plugin and theme you’re using supports the new WordPress version. Most responsible developers keep their products current, but some sites still rely on abandoned plugins that haven’t been touched in years.

Action step: Create a list of every plugin installed on your site. Check the official WordPress plugin directory to confirm compatibility with the latest version. If a plugin hasn’t been updated in over a year, start looking for a replacement now—not after an update breaks it.

Data Loss During the Update Process

The security risks of updating WordPress include the possibility of losing data if something interrupts the process. While rare, an interruption during an update—like an internet dropout or server timeout—can leave your database in an inconsistent, corrupted state.

Some hosting providers have slower servers that don’t complete updates within the timeout window. At that point, your site is trapped in limbo: it doesn’t have the security patch, but it’s not stable either.

The solution is straightforward: always create a complete backup before updating. If something fails, you restore your site to its previous state in minutes.

Action step: Use a plugin like UpdraftPlus or BackWPup to automate backups. Don’t rely on “remembering to do it.” Automated backups run without requiring you to think about them, and they’re your most important safety net.

Vulnerable Outdated Plugins Create Major Exposure

This is where many business owners make a critical mistake. You update WordPress but leave your plugins sitting on old versions—creating a security weak point. Plugins are the favorite target of hackers because so many site owners forget about them.

According to Wordfence’s security research, most breaches on WordPress sites come from vulnerable plugins, not from WordPress core itself. If you’re running an outdated ecommerce plugin, attackers could potentially access your customers’ payment information. The risk multiplies when you update WordPress but plugins become incompatible with the new version. Some site owners simply disable the incompatible plugins and call it done—leaving a system with security holes.

Deprecated Functions and API Changes

WordPress evolves every update, marking older functions as deprecated. If your site uses custom code or poorly built plugins that rely on those old functions, errors emerge. These aren’t always obvious immediately. You update WordPress, the site looks fine for a week, then suddenly email doesn’t send, search breaks, or image uploads fail.

These deprecated functions can also create security problems if custom code tries to work around them in unsafe ways.

How to Actually Minimize Update Risks

Set Up a Staging Environment

The safest way to update WordPress is having a test site that mirrors your live one exactly. Most quality hosting providers like SiteGround or Kinsta offer built-in staging environments.

Update on your staging site first. Test all plugins, themes, and custom features thoroughly. Only after confirming everything works do you update your live site.

This one extra step saves hours of stress and potentially thousands in revenue loss if something goes sideways.

Action step: If your current hosting doesn’t offer staging, request it. It’s a standard feature with any professional provider. If they say no, that’s a sign you might need better hosting.

Update Frequently, Not All at Once

Don’t let WordPress, plugins, and themes fall so far behind that updating becomes riskier than staying vulnerable. Update regularly—weekly or biweekly is ideal.

Small, frequent updates are exponentially less risky than trying to leap several versions at once after months of neglect. Plus, you close security gaps before attackers have time to exploit them.

Monitor Your Site Immediately After Updating

Spend 15 minutes checking your site after each update. Test contact forms, verify your shopping cart works (if you sell online), confirm images load correctly, and check for console errors.

Use Google Search Console to watch for crawl errors after updating. Sometimes changes affect URL structures or breadcrumbs, which can hurt your SEO.

Frequently Asked Questions

How often should I update WordPress?

Update security patches within 24-48 hours of release. Minor and feature updates can wait longer, but security patches shouldn’t. In 2026, vulnerabilities are discovered and exploited faster than ever before.

What’s riskier—not updating or updating wrong?

Not updating is riskier long-term. Your site stays exposed to known, actively exploited vulnerabilities. Updating incorrectly might cause temporary problems, but you’ve at least closed the security hole. With proper strategy (backup, staging environment), bad updates are recoverable. No updates is a disaster waiting to happen.

Can I automate WordPress updates completely?

You can automate minor plugin and theme updates—that’s reasonably safe. Major WordPress core updates should stay manual, with a backup in place and testing on staging first. Full automation can create problems you won’t notice until they’re serious.
