Introduction

WordPress 7.0.4 is now available as an important security release for WordPress websites. Released on August 12, 2026, the update addresses a serious security vulnerability involving authenticated users, malicious file uploads, and websites using Imagick and Ghostscript. WordPress recommends that site owners update their websites as soon as possible. (WordPress.org)

Unlike a major WordPress release that introduces a large collection of new features, a security release such as 7.0.4 is primarily concerned with protecting existing websites. These updates can be easy to overlook because they may not visibly change the appearance of a website, but they can be extremely important for preventing attackers from exploiting known weaknesses.

This article explains what WordPress 7.0.4 contains, why the security fix matters, who may be affected, how to update safely, and what additional steps website administrators should take after installing the update.

What Is WordPress 7.0.4?

WordPress 7.0.4 is a minor security release in the WordPress 7.0 series. It was officially released on August 12, 2026 and contains a security fix related to malicious file uploads.

According to the official WordPress announcement, the vulnerability can potentially allow an authenticated user with Author-level privileges or higher to achieve remote code execution on a vulnerable configuration involving Imagick and Ghostscript. (WordPress.org)

WordPress has assigned the issue:

CVE: CVE-2026-65640
GHSA: GHSA-8vr3-7mxf-gx8w
Affected area: Malicious file upload processing
Potential impact: Remote code execution
Relevant software: Imagick and Ghostscript
Reported by: pwn.ai (WordPress.org)

Because remote code execution vulnerabilities can potentially give an attacker the ability to execute commands or code on a server, website administrators should treat this update as a priority.

Why WordPress 7.0.4 Is Important

Security vulnerabilities are particularly dangerous when they involve the ability to execute code on a server.

A typical WordPress website allows authorized users to upload media such as:

Images
Documents
PDFs
Other supported media files

WordPress and the underlying server environment process uploaded files using different libraries and tools. In certain configurations, image-processing software can introduce additional security risks.

The WordPress 7.0.4 fix addresses a vulnerability involving Imagick and Ghostscript that could be exploited through a malicious file upload by an authenticated Author-level user or someone with greater privileges. (WordPress.org)

The practical lesson for administrators is simple:

A user does not necessarily need to be a site administrator for a vulnerability involving file processing to become a serious security concern.

WordPress 7.0.4 Security Fix Explained

Authenticated Author+ Remote Code Execution

The primary security issue fixed in WordPress 7.0.4 is described as:

Authenticated Author+ remote code execution via malicious file upload on sites that use Imagick and Ghostscript. (WordPress.org)

Let’s break that description down.

What Does “Authenticated” Mean?

An authenticated user is someone who has successfully logged into the WordPress website.

This is different from an unauthenticated attack, where the attacker does not need an account.

In this particular vulnerability, the attacker needs an account with sufficient privileges.

What Does “Author+” Mean?

“Author+” means an account with Author-level privileges or higher.

Depending on the site’s configuration, this can include roles such as:

Author
Editor
Administrator

This is important for websites that have multiple contributors, writers, editors, freelancers, or agency users.

What Is Remote Code Execution?

Remote Code Execution, commonly abbreviated as RCE, refers to a situation where an attacker can cause a computer or server to execute malicious code remotely.

RCE vulnerabilities are generally considered serious because successful exploitation can potentially allow an attacker to:

Modify website files
Access sensitive information
Create malicious content
Install unauthorized code
Change website behavior
Establish persistence
Potentially compromise other parts of the hosting environment

The actual impact depends on the server configuration, permissions, installed software, and other security controls.

How Imagick and Ghostscript Fit Into the Problem

To understand the issue, it helps to know what these technologies do.

What Is Imagick?

Imagick is a PHP extension that provides an interface to ImageMagick, a widely used image-processing system.

Web applications can use it for tasks such as:

Resizing images
Converting image formats
Creating thumbnails
Processing uploaded graphics
Manipulating image files

WordPress websites can encounter Imagick through their hosting environment and PHP configuration.

What Is Ghostscript?

Ghostscript is software commonly associated with processing formats such as PostScript and PDF.

It is useful for handling certain document and image-processing operations, but software that interprets complex file formats can become a security concern when maliciously crafted files are processed.

The WordPress 7.0.4 advisory specifically identifies configurations using Imagick and Ghostscript in relation to the vulnerability. (WordPress.org)

Who Should Update to WordPress 7.0.4?

The safest approach is for website owners running WordPress 7.0.x to update promptly.

This is particularly important for:

Business websites
News websites
Membership websites
WooCommerce stores
Multi-author blogs
Agency websites
Websites accepting contributor uploads
Websites where multiple users have WordPress accounts
Websites using image-processing functionality

Even if you believe your website is unlikely to be targeted, security updates should not normally be postponed unnecessarily.

WordPress explicitly recommends immediate updating because this is a security release. (WordPress.org)

WordPress 7.0.4 vs. Previous 7.0 Releases

The 7.0 branch has already received several maintenance and security updates during 2026.

For example, WordPress 7.0.1 was a maintenance release that addressed bugs across Core and the Block Editor. WordPress 7.0.2 was subsequently released as a security update addressing serious security issues. (WordPress.org)

WordPress 7.0.4 continues this maintenance cycle with another security-focused update.

Simplified release timeline

Version	Date	Main Purpose
WordPress 7.0	May 20, 2026	Major release
WordPress 7.0.1	July 9, 2026	Maintenance
WordPress 7.0.2	July 17, 2026	Security
WordPress 7.0.3	August 6, 2026	Security
WordPress 7.0.4	August 12, 2026	Security

WordPress’ official release information confirms the 7.0 series and its maintenance history. (WordPress.org)

How to Update to WordPress 7.0.4

Updating WordPress is normally straightforward.

Method 1: Update From the WordPress Dashboard

Step 1: Log In

Step 2: Open Updates

Navigate to:

Dashboard → Updates

WordPress should display information about available updates.

Step 3: Locate the WordPress Core Update

Look for the available WordPress update.

If your website is eligible for the update, you should see an option to update WordPress.

Step 4: Click “Update Now”

Click Update Now and allow WordPress to complete the process.

The official WordPress announcement confirms that WordPress 7.0.4 can be installed from the Dashboard → Updates section. (WordPress.org)

Step 5: Check the Version

After the update finishes, verify that your website is running the expected WordPress version.

You can usually check this from the WordPress dashboard or site information area.

Should You Back Up Your Website Before Updating?

Yes.

Although WordPress minor updates are designed to be relatively safe, creating a backup before any software update is a good maintenance practice.

Your backup should ideally include:

Website Files

Back up:

WordPress core files
Themes
Plugins
Uploads
Custom files
Configuration files

Database

Also create a backup of your WordPress database.

The database can contain:

Posts
Pages
Users
Settings
Comments
WooCommerce information
Plugin data

A complete backup gives you a recovery option if an unexpected compatibility issue occurs.

What to Check After Installing WordPress 7.0.4

Do not simply update WordPress and immediately leave the website.

Perform a quick post-update check.

1. Open the Homepage

Visit the public website and confirm that the homepage loads normally.

2. Test Important Pages

Check:

About page
Contact page
Services pages
Blog
Product pages
Landing pages

3. Test the WordPress Dashboard

4. Test Forms

If your website uses contact or lead forms, submit a test message.

5. Check Media Uploads

Because this release addresses a vulnerability related to malicious file uploads, it is sensible to verify that legitimate media uploads continue to function as expected.

6. Check Your Plugins

Look for plugin updates and compatibility warnings.

7. Check Your Theme

If your website uses a custom theme, visit several pages and make sure there are no layout or functionality problems.

What Website Owners Should Do Beyond the Core Update

Installing WordPress 7.0.4 is important, but website security should not stop there.

Keep Plugins Updated

Outdated plugins are one of the common maintenance concerns for WordPress administrators.

Only install plugins from reputable sources and remove plugins that are no longer required.

Keep Themes Updated

An outdated theme can create security and compatibility problems.

If you have unused themes installed, consider removing them rather than leaving unnecessary software on the website.

Review User Accounts

Because the 7.0.4 vulnerability involves authenticated Author-level users or higher, user management deserves particular attention.

Review your WordPress users and ask:

Does every account still need access?
Are former employees still listed?
Are old writers still active?
Does every contributor need Author privileges?
Are administrator accounts protected with strong passwords?
Are there unnecessary accounts that can be removed?

Reducing unnecessary privileges is an important security principle.

Use Strong Authentication

Every WordPress account should use a strong, unique password.

For administrators and other privileged users, adding multi-factor authentication where supported can provide another layer of protection.

A strong security setup should combine:

Strong passwords + least privilege + updates + backups + monitoring

No single security feature can protect a website against every possible attack.

Why Security Updates Should Not Be Ignored

It can be tempting to postpone WordPress updates because the website appears to be working correctly.

However, a website can operate normally while containing a known security vulnerability.

The danger increases after a vulnerability becomes publicly documented because security researchers, defenders, and malicious actors can all study the same information.

That is why WordPress recommends updating promptly when security releases are published.

WordPress’ supported-version documentation also explains that security fixes may be backported to older branches as a courtesy, while the most recent major release is the officially supported version. (WordPress.org)

Does WordPress 7.0.4 Add New Features?

No major new feature should be the primary reason for installing WordPress 7.0.4.

This release is specifically presented by WordPress as a security release.

Its main purpose is to fix the vulnerability rather than introduce a large collection of user-facing features. (WordPress.org)

That distinction matters.

Major release

Usually focuses on:

New features
Editor improvements
Performance changes
Developer functionality
User experience

Maintenance release

Usually focuses on:

Bug fixes
Stability
Compatibility
Smaller improvements

Security release

Primarily focuses on:

Vulnerability fixes
Security hardening
Protecting users from known attack techniques

WordPress 7.0.4 belongs to the third category.

What Happens If You Don’t Update?

There is no guarantee that an outdated website will be attacked.

However, remaining on a vulnerable version leaves the site exposed to the weakness addressed by the security update.

Potential consequences of a successful website compromise can include:

Website defacement
Malware
Spam pages
Unauthorized administrator accounts
Data theft
Search-engine spam
Redirects to malicious websites
Loss of customer trust
Hosting-account suspension
Recovery and cleanup costs

For business websites, the consequences can extend beyond the technical problem.

A compromised website can damage a company’s reputation and interrupt normal operations.

Is WordPress 7.0.4 Safe to Install?

WordPress 7.0.4 is an official WordPress security release, and the project recommends updating sites immediately. (WordPress.org)

As with any software update, website owners with heavily customized installations should still follow a sensible backup and testing process.

If the website is business-critical, you can first test the update on a staging environment before deploying it to production.

For ordinary WordPress installations, however, delaying a security update without a good reason is generally not recommended.

What About Older WordPress Versions?

WordPress says that the 7.0.4 security fix is being backported through the 4.7 branch, with backports shipping as they become ready. The WordPress team also reminds users that only the most recent version is actively supported. (WordPress.org)

This is important for organizations that operate older WordPress installations.

If your website is running an older branch, don’t assume that it will remain protected forever simply because a historical branch sometimes receives security fixes.

A better long-term strategy is to maintain a supported WordPress version and plan upgrades before the software becomes outdated.
