Learn why keeping WordPress, plugins, and themes updated is essential for your site's security, stability, and performance.

It can be tempting to skip updates — they feel risky, and the site seems to be working fine. But WordPress's own security guide names attacks on outdated plugins and software as one of the most common ways WordPress sites are attacked. This guide explains what's really at stake and why staying current matters.

Quick summary

Outdated software is one of the most common ways into a WordPress site. Updates fix known security holes before attackers can exploit them. Staying current is the most important thing you can do to keep your site safe.

What updates actually fix

When developers release an update, they're usually fixing one of three things:

Security vulnerabilities — A flaw in the code that could let someone gain unauthorized access to your site or its data.
Bugs — Errors in the software that cause unexpected behavior.
Compatibility issues — Problems that arise when one piece of software doesn't work well with another (like a plugin conflicting with a new WordPress version).

Most updates are routine maintenance. Security updates are urgent.

The risk of outdated software

When a security vulnerability is discovered in a plugin or in WordPress itself, two things happen at the same time:

The developers release a patch (an update that fixes it).
The vulnerability often becomes public knowledge — meaning attackers know about it too.

Anyone still running the old version is now exposed. Many attacks are run by automated bots that look for sites running vulnerable software versions. It's not personal — your site is just on a list.

Outdated plugins are a common entry point

WordPress's own security guide says one of the most common kinds of attack targets known holes in old or outdated plugins and software, and it tells site owners to keep plugins updated. A site with ten outdated plugins has ten potential doors that attackers can try.

What happens if your site gets hacked?

The consequences can be serious:

Malware injected into your site — Putting visitors' devices at risk.
Your site gets flagged by Google and others — Visitors can see a warning page telling them to stay away, and search results can show warnings too.
Spam sent from your site — Email blocklists can flag your server, damaging your email reputation.
Data stolen — Customer information, form submissions, or credentials.
Downtime and recovery costs — Cleaning a hacked site takes significant time and money.

Prevention through updates is far less costly than recovery.

Updates also improve your site

Security aside, updates also:

Fix broken features
Add compatibility with new browsers and devices
Improve performance
Introduce new capabilities

Keeping current means your site benefits from ongoing improvements, not just security patches.

This is why we keep things updated

If you're on one of our care plans, keeping your site's software current is one of the core things we do. We monitor for updates, test them, and apply them — so you don't have to think about it.

"Set it and forget it" is the goal. Your site should be maintained in the background so you can focus on running your business.

If you manage your own updates, read What to do before a big update and How to update plugins safely.

A note on "my site is working fine"

A compromised site can look perfectly normal to you. Attackers don't want to be noticed. They may quietly use your site to send spam or spread malware — while you see nothing unusual.

Regular updates and security monitoring (checking for unexpected changes) are both important. They work together.

Common questions

If I update everything, can my site break?

Sometimes, yes — often because a plugin isn't yet compatible with a new WordPress version. This is why we always back up first and test major updates. The risk of not updating is far greater than the risk of a fixable compatibility issue.

How quickly do I need to apply a security update?

As soon as reasonably possible — ideally the same day or within a day or two. Security updates are released precisely because a known vulnerability exists. The longer you wait, the more exposure you have.

Does WordPress update itself automatically?

Partly. By default, WordPress installs minor (maintenance and security) releases automatically. Sites first installed on WordPress 5.6 or later also get major releases automatically; older sites need someone to run them or switch that on. Plugins and themes update themselves only if auto-updates are switched on for each one. Your host or a plugin can change any of these settings. See WordPress updates explained for the full picture.

What if I'm afraid updates will break something?

This is what backups and staging sites are for. A good pre-update routine (back up, update on staging, then apply to live) greatly reduces the risk. We do this as standard for our care plan clients.
