Keeping a WordPress website updated is one of the simplest and most important steps you can take to maintain website security, stability, and performance. On August 12, 2026, WordPress released version 7.0.4, and this is a security release that WordPress recommends installing immediately.
Unlike a major WordPress release that may introduce numerous new features, WordPress 7.0.4 focuses on fixing a security vulnerability. This makes the update particularly important for businesses, developers, agencies, and website owners running WordPress 7.0 or affected older versions.
In this guide, we’ll explain what WordPress 7.0.4 includes, why the update matters, how to update your website safely, and what you should check after the update.
What Is WordPress 7.0.4?
WordPress 7.0.4 is a security update released for the WordPress 7.0 branch. The official WordPress documentation states that the release contains several security fixes and recommends updating websites immediately.
The update was released on August 12, 2026, and can be installed directly from the WordPress Dashboard under Updates → Update Now. Websites that support automatic background updates may also receive the update automatically.
For website owners, the important point is simple: WordPress 7.0.4 is primarily a security update, not a feature-focused release.
Why Is WordPress 7.0.4 Important?
Security updates should generally be treated differently from optional feature updates.
The WordPress 7.0.4 release addresses an authenticated remote code execution vulnerability involving malicious file uploads on websites using Imagick and Ghostscript. WordPress identifies the issue as CVE-2026-65640 / GHSA-8vr3-7mxf-gx8w.
The issue affects users with sufficient authentication privileges under the vulnerable configuration.
This doesn’t mean that every WordPress website is automatically compromised. However, leaving a known security issue unpatched unnecessarily increases risk.
For business websites containing customer information, enquiry forms, eCommerce functionality, administrator accounts, or other important data, keeping the WordPress core updated should be part of regular website maintenance.
Before Updating WordPress 7.0.4
Although WordPress updates are usually straightforward, it’s good practice to take a few precautions before updating a production website.
1. Take a Complete Backup
The first step should be creating a current backup.
Ideally, your backup should include:
- WordPress database
- Themes
- Plugins
- Media uploads
- WordPress core files
- Configuration files
Having a recent backup gives you a recovery option if an unexpected compatibility issue occurs.
For an important business website, don’t rely on an old backup from several weeks or months ago.
2. Check Your Current WordPress Version
Before updating, check which version your website is currently running.
You can usually find this information from:
WordPress Dashboard → Updates
You may also see the installed version in the WordPress administration area.
If your website is already running WordPress 7.0.4, no additional core update is required.
If you’re running an older version, you should determine the appropriate supported security release for your branch. WordPress has also provided backported fixes for several older branches affected by the vulnerability.
3. Check Your Plugins
Plugins extend WordPress functionality, but they can also create compatibility problems when the core software changes.
Before updating, check whether your important plugins are:
- Actively maintained
- Updated recently
- Compatible with your WordPress version
- Free from known errors
Pay particular attention to plugins that are essential to your business, such as:
- WooCommerce
- Contact forms
- SEO plugins
- Security plugins
- Payment gateways
- Booking systems
- Membership plugins
- Custom functionality
You don’t necessarily need to disable every plugin before a normal security update, but understanding your website’s dependencies is good maintenance practice.
4. Check Your Theme
The same applies to your WordPress theme.
If you’re using a commercial theme, check whether the developer has released a recent update.
If your website uses a custom WordPress theme, review the site’s functionality after the core update.
Custom themes can contain integrations and code that aren’t present in standard WordPress installations, so testing is particularly important for complex business websites.
How to Update to WordPress 7.0.4
For most websites, the easiest method is through the WordPress Dashboard.
Step 1: Log in to WordPress
Go to your WordPress administration area.
Step 2: Open Updates
Navigate to:
Dashboard → Updates
Step 3: Look for WordPress 7.0.4
If the update is available, WordPress should display the available version.
Step 4: Click “Update Now”
Select Update Now and allow WordPress to complete the process.
The official WordPress instructions specifically identify the Dashboard → Updates → Update Now process as the standard update method.
Step 5: Wait for Completion
Don’t close the browser or interrupt the process while WordPress is updating.
Once the update is complete, WordPress should return you to the administration area.
Should You Update Directly on a Live Website?
For a simple website with a standard theme and well-maintained plugins, updating through the Dashboard is generally straightforward.
However, larger or more complex websites deserve additional caution.
For example:
- WooCommerce stores
- Membership websites
- Large corporate websites
- Custom WordPress applications
- Websites with many third-party integrations
- Websites using custom themes
- Websites with significant custom code
For these projects, testing the update on a staging website before applying it to production can reduce the risk of unexpected problems.
A staging environment allows developers to update WordPress and test important functionality before visitors interact with the updated production website.
What Should You Check After the Update?
Don’t assume everything is working simply because WordPress reports that the update completed successfully.
Spend a few minutes testing your website.
Check the Homepage
Make sure:
- The homepage loads correctly
- Images appear properly
- Navigation works
- Fonts and layouts look normal
- No unexpected error messages appear
Check Important Pages
Visit your:
- About page
- Services pages
- Contact page
- Blog
- Portfolio
- Product pages
- Location pages
The exact pages will depend on your website.
Test Contact Forms
If your website generates leads, test your contact forms.
Make sure:
- The form submits successfully
- Validation works
- Confirmation messages appear
- Emails are delivered correctly
This is particularly important for business websites because a broken enquiry form can directly affect lead generation.
Check eCommerce Functionality
If your website uses WooCommerce, test critical customer journeys such as:
- Product pages
- Add to cart
- Cart
- Checkout
- Payment gateway
- Customer login
- Order confirmation
For an online store, even a small compatibility issue can have a significant business impact.
Don’t Forget About Caching
After updating WordPress, your caching system may continue serving older versions of certain files.
If you use:
- WordPress caching plugins
- LiteSpeed Cache
- Server-side caching
- CDN caching
- Cloud-based caching
clear the appropriate cache after completing the update.
Then reload the website and test it again.
What About Plugins and Themes?
Updating WordPress core doesn’t automatically mean that every plugin and theme should be updated at exactly the same moment.
It’s better to understand what each update does.
For important websites, a sensible maintenance process is:
Backup → Test → Update → Check → Monitor
Rather than blindly updating everything at once.
If a plugin update is also available, review its changelog and compatibility information before installing it.
What If the Website Breaks After Updating?
Don’t panic.
If something stops working after an update, first identify what changed.
Possible causes include:
- Plugin incompatibility
- Theme compatibility issue
- Custom code
- PHP compatibility
- Caching problems
- JavaScript errors
- Third-party integrations
If you have a recent backup or staging environment, troubleshooting becomes much easier.
For complex websites, a WordPress developer can review server logs, PHP errors, plugin conflicts, and custom code to identify the cause.
Does WordPress 7.0.4 Improve SEO?
WordPress 7.0.4 is a security release, so it shouldn’t be treated as a direct SEO update. Its primary purpose is addressing security issues rather than introducing a new SEO feature set.
However, website security is an important part of maintaining a healthy website.
A compromised website can potentially experience:
- Spam pages
- Malicious redirects
- Unauthorized content
- Suspicious scripts
- Search engine warnings
- Loss of visitor trust
Keeping WordPress updated is therefore part of maintaining the overall technical health of a website.
WordPress Updates Should Be Part of Regular Maintenance
One of the biggest mistakes businesses make is treating website development as a one-time project.
A website may be designed and launched successfully, but it still requires ongoing maintenance.
Regular WordPress maintenance can include:
- WordPress core updates
- Plugin updates
- Theme updates
- Security monitoring
- Backup verification
- Performance optimization
- Database maintenance
- Broken-link checks
- Form testing
- Malware monitoring
This is particularly important for websites that generate leads or revenue.
What If You’re Running an Older WordPress Version?
If your website isn’t running WordPress 7.0, don’t simply assume that installing 7.0.4 is always the correct approach without checking your current branch and compatibility.
The official WordPress documentation notes that the 7.0.4 security fix has been backported to multiple older supported branches. It also states that only the most recent version is actively supported.
Therefore, if your website is significantly outdated, it’s worth reviewing the upgrade path rather than performing a major version jump without preparation.
Older websites may also have outdated themes, plugins, PHP versions, or custom code that need attention.

Final Thoughts
WordPress 7.0.4 is an important security update released on August 12, 2026. WordPress recommends updating sites immediately because the release addresses a security vulnerability involving authenticated remote code execution through malicious file uploads in specific Imagick/Ghostscript configurations.
For most websites, updating through Dashboard → Updates → Update Now is straightforward. However, businesses running complex WordPress websites should take a more careful approach by creating backups, checking plugin and theme compatibility, testing critical functionality, and monitoring the website after the update.
A secure WordPress website isn’t maintained through one update alone. Regular updates, backups, security checks, performance monitoring, and professional maintenance all contribute to a healthier website.
For businesses using WordPress as an important part of their online presence, professional WordPress Website Development and ongoing maintenance can help ensure that the website remains secure, reliable, fast, and ready to support business growth.
The best time to check your WordPress version is before a security problem occurs—not after.
