WordPress Security Update 7.0.2: How to Check, Update and Verify a Hosted Website

WordPress 7.0.2 Security Update: What It Fixes and How to Update Safely

If you manage a WordPress website, security updates are not something you should put off for weeks. WordPress 7.0.2 was released on July 17, 2026, as a security release addressing two reported security issues, including a critical issue involving SQL injection and a high-severity issue involving REST API batch routes that could lead to SQL injection and remote code execution.

For website owners, the important question is simple: Is your WordPress website affected, and what should you do about it?

If your website is still running an affected WordPress version, you should update it. However, there is an important detail to keep in mind if you are reading this after the original 7.0.2 release: WordPress 7.0.3 was released on August 6, 2026 and includes additional security fixes. If your WordPress dashboard offers a newer stable version, install the latest stable release instead of deliberately staying on 7.0.2.

What is WordPress 7.0.2?

WordPress 7.0.2 is a security-focused WordPress release published on July 17, 2026. The release addressed security vulnerabilities affecting certain WordPress versions and was accompanied by a recommendation from WordPress.org to update affected installations.

One of the reported issues involved a facilitated SQL injection vulnerability. Another involved confusion around REST API batch routes, with potential consequences including SQL injection and remote code execution.

That may sound highly technical if you are simply running a business website, blog or online store. In practical terms, the takeaway is much easier:

If your website is running an affected version of WordPress, keeping it updated reduces exposure to known security problems.

WordPress installations that support automatic background updates may receive security updates without requiring the site owner to manually click the update button. Even so, it is worth checking the installed version and confirming that the website continues to work after an update.

Do I still need WordPress 7.0.2?

This is one of the most important things to understand about an older security release.

If you are checking your website today and WordPress is offering a newer stable 7.0.x release, you generally should not manually install the older 7.0.2 package simply because that is the version mentioned in an article.

WordPress 7.0.3 was released on August 6, 2026 and includes additional security fixes. Therefore, the practical approach is to open your WordPress dashboard and install the latest stable version offered for your installation.

The 7.0.2 release is still important because it explains the security issues that prompted the update, but your goal as a website owner should be to keep the site on a current supported release rather than freeze it at an older security version.

Which WordPress versions were affected?

According to the WordPress 7.0.2 release information, WordPress 6.9 was affected by both reported vulnerabilities and received fixes in version 6.9.5.

WordPress 6.8 was affected by the first reported issue and received a fix in version 6.8.6. Versions older than WordPress 6.8 were not affected by these specific vulnerabilities according to the release information.

WordPress 7.1 beta 2 also received fixes.

If you are unsure which version your website is using, do not guess. Check the version directly from the WordPress administration area.

How to check your WordPress version

You can check the installed version without touching your website files.

1. Log in to your WordPress administrator dashboard.
2. Open Dashboard → Updates.
3. Look for the currently installed WordPress version.
4. Check whether a newer stable WordPress release is available.
5. Review any available plugin and theme updates as well.

If you manage the server yourself and use WP-CLI, you can also check the version from the WordPress installation directory:

wp core version

WP-CLI can be useful for developers and server administrators, but make sure you run commands with the appropriate Linux user and permissions for the WordPress installation.

Why is this security update important?

WordPress security is not limited to WordPress core.

A typical website consists of several moving parts:

• WordPress core
• Plugins
• The active theme
• PHP
• The database
• The web server
• Hosting control-panel software
• File and directory permissions

Updating WordPress core fixes problems in WordPress itself, but it does not automatically make an outdated plugin secure. The same applies to themes, PHP versions and server software.

That is why a WordPress security update should be treated as part of regular website maintenance rather than as a one-time task.

How to update WordPress 7.0.2 safely

For most websites, updating WordPress is straightforward. The part that deserves more attention is what you do before and after pressing the update button.

Step 1: Check the current version

Start by opening:

Dashboard → Updates

Check your current WordPress version and see which version WordPress is offering.

If a newer stable security release is available, use that version instead of manually installing an older release.

Step 2: Take a complete backup

Before making a significant change to a production website, create a backup.

A proper WordPress backup should include both:

• Website files — including plugins, themes and media uploads.
• Database — including posts, pages, users, settings and plugin data.

Your hosting provider may offer backups through a control panel, while other websites use a dedicated WordPress backup plugin or server-level backup system.

The important part is not simply seeing a message saying “Backup completed.” You should also know where the backup is stored and how you would restore it if the update caused a problem.

For an important business or e-commerce website, consider testing the update on a staging copy first.

Step 3: Update WordPress from the dashboard

For a normal WordPress installation, the dashboard is usually the easiest way to perform the update.

1. Open Dashboard → Updates.
2. Review the available WordPress version.
3. Make sure your backup has completed.
4. Click Update Now.
5. Wait for WordPress to finish the update.
6. Return to the dashboard and confirm the installed version.

Do not close the browser or interrupt the process while WordPress is performing the update.

WordPress core files are replaced during an update. If you have made direct modifications to WordPress core files, those changes may be overwritten. Custom functionality should normally be implemented through a plugin or an appropriate child-theme setup rather than by modifying core files directly.

What if the automatic WordPress update does not work?

Most website owners should try the normal dashboard update first. Manual updating is mainly useful when the automatic process fails or when the website is managed through a controlled server deployment process.

A manual update requires more care because you are working directly with the site's files.

If you have to perform a manual update, obtain WordPress only from the official WordPress source and follow the documented update procedure. Be especially careful with:

• wp-content
• wp-config.php
• File ownership
• File permissions
• The correct WordPress document root

Never replace a failed update by blindly deleting WordPress directories. If you are not comfortable working with FTP, SSH or a hosting file manager, it is safer to ask your hosting provider or an experienced WordPress administrator for help.

Should you update plugins and themes too?

Yes, but take a sensible approach.

After updating WordPress core, open:

Dashboard → Plugins

and:

Appearance → Themes

Look for available updates and check compatibility information where it is provided.

For a simple blog, updating several compatible components may be relatively low risk. For a business website, membership website or online store, however, it can be easier to troubleshoot problems when you change one important component at a time.

Pay particular attention to plugins that control:

• Payment processing
• WooCommerce
• Page builders
• Forms
• Security
• Caching
• SEO
• Custom functionality

Also remove plugins and themes that you no longer need. Leaving unused software on a website creates additional maintenance and security overhead.

What should you test after updating WordPress?

A successful update message does not necessarily mean every feature on the website is working.

Spend a few minutes checking the important parts of the site.

• Open the homepage.
• Visit several important pages.
• Check the WordPress login.
• Log in and log out.
• Test contact forms.
• Check images and media.
• Test website search.
• Check menus and navigation.
• Test downloads if your site provides files.
• Test checkout and payment functionality on an e-commerce website.
• Confirm that HTTPS is working correctly.
• Check for unexpected PHP or server errors.

If your website uses caching, give the cache system a chance to refresh. You may need to clear the WordPress page cache or CDN cache if an old version of a page continues to appear.

What to do if WordPress gets stuck in maintenance mode

One possible problem after an interrupted WordPress update is a website that continues displaying a maintenance message.

WordPress can create a .maintenance file in the site's root directory during the update process. If the update has definitely stopped and the website remains stuck in maintenance mode, an administrator can check for that file.

If the update process is no longer running, the file can be removed through the hosting file manager, FTP or SSH.

Be careful when working directly inside the WordPress root directory. Delete only the specific maintenance file and do not remove unrelated WordPress files.

What if WordPress shows a critical error after the update?

A critical error after a WordPress update does not automatically mean WordPress core is broken.

A plugin or theme may be incompatible with the updated version.

Start by checking the PHP error log and identifying which component generated the error. If you recently updated a plugin, temporarily disabling that plugin can help confirm whether it is responsible.

If you cannot access the WordPress dashboard, you may need to use the hosting file manager, SSH or another server-management method to disable the suspected plugin.

Avoid randomly changing PHP versions, deleting plugins or modifying production files before identifying the actual error. That can turn a small compatibility problem into a much larger one.

Why is WordPress asking for FTP credentials?

This usually points toward a file ownership or permission problem.

WordPress needs permission to write to the files it manages. If the web server user cannot modify the necessary files, WordPress may ask for FTP credentials during an update.

This is particularly common on incorrectly configured VPS installations or websites that have recently been migrated between servers.

Do not solve the problem by giving everything 777 permissions. Broad write permissions can create unnecessary security risks.

Instead, check the correct owner, group and permissions for the WordPress installation.

Why is the WordPress update button missing?

There are several possible reasons.

The website may already be running the current version. An automatic background update may have completed. Alternatively, the WordPress installation could be managed through a hosting control panel.

Start by checking the version displayed in the WordPress dashboard and refreshing the Updates page.

If WordPress cannot communicate with its update servers, security software, firewall rules or outbound network restrictions can sometimes interfere with update checks.

What if the website becomes slow after the update?

A website can temporarily behave differently after an update while caches are rebuilt or background tasks are processed.

If the slowdown continues, check:

• PHP error logs
• Server CPU usage
• Available RAM
• Disk space
• Database activity
• WordPress scheduled tasks
• Plugin performance

Do not immediately assume that the WordPress core update is responsible. Compare the timing of the slowdown with other changes made to the website.

How hosting affects WordPress security updates

Your hosting environment plays a bigger role in WordPress maintenance than many website owners realise.

A suitable hosting environment should provide enough storage for backups, support the PHP and database versions your website requires, and give you access to useful logs and recovery options.

Shared hosting can work well for many smaller WordPress websites. A VPS becomes more useful when you need greater control over the operating system, custom software, isolated resources or server-level configuration.

However, moving to a VPS does not automatically make WordPress more secure. With greater control comes greater responsibility. On a VPS, you may also be responsible for operating-system updates, firewall configuration, server security, backups and permissions.

WordPress 7.0.2 security update FAQ

Is WordPress 7.0.2 safe?

WordPress 7.0.2 was released as a security update addressing reported vulnerabilities. However, if your website is being updated now and a newer stable release is available, use the newer release rather than intentionally installing 7.0.2.

Do I need to update if WordPress already updated automatically?

Check the installed WordPress version. If the security update was installed automatically, there may be nothing else you need to do for that particular core release. It is still worth checking the website and making sure important functionality works normally.

Will a WordPress security update delete my posts?

A normal WordPress core update is not intended to delete your posts, pages or media. However, you should always maintain a reliable backup because update failures, incompatible plugins, server problems and configuration issues can happen.

Should I disable plugins before updating WordPress?

Usually, you do not need to disable every plugin before performing a normal WordPress core update. If a specific plugin is known to cause compatibility problems, temporarily disabling it may be appropriate.

Can I update WordPress without a backup?

You can, but it is not a sensible approach for an important website. A recent backup gives you a recovery option if something goes wrong during or after the update.

What is the safest way to update WordPress?

For most websites, the practical process is simple: check the current version, create a reliable files-and-database backup, update through the WordPress dashboard, then test the important website functions.

WordPress security update checklist

Before finishing your maintenance work, run through this list:

• ✓ Check the installed WordPress version.
• ✓ Check whether a newer stable release is available.
• ✓ Create a complete website and database backup.
• ✓ Update WordPress core.
• ✓ Check plugins and themes for compatible updates.
• ✓ Test the homepage and important pages.
• ✓ Test forms, login and other important functionality.
• ✓ Test checkout if the website sells products or services.
• ✓ Check HTTPS.
• ✓ Review PHP and server logs if anything looks unusual.
• ✓ Confirm that the backup can actually be restored.

Final thoughts

WordPress security updates are easiest to manage when they become part of your normal website maintenance routine. You do not need to panic every time WordPress publishes a security release, but you also should not ignore one indefinitely.

WordPress 7.0.2 addressed important security issues, including vulnerabilities involving SQL injection and REST API batch-route handling. Since a newer 7.0.3 release followed it, website owners checking their installations now should focus on running the latest stable release available for their site rather than manually staying on 7.0.2.

The safest workflow is straightforward: check your version, keep a restorable backup, apply the current security update, and test the website afterward.

And remember that WordPress core is only one part of the security picture. Keep plugins, themes, PHP and the hosting environment maintained as well. A properly updated WordPress installation is much easier to manage when the underlying hosting environment is also kept in good condition.
