WordPress 7.1.3 Update: Key Security Fixes Explained

WordPress 7.1.3: What’s New in the Latest Maintenance and Security Release

WordPress has released WordPress 7.1.3, the latest maintenance and security update for the WordPress 7.1 series. Released on October 6, 2026, this update includes 7 security fixes and 4 bug fixes.

Because WordPress 7.1.3 is a security release, website owners are encouraged to update their WordPress websites as soon as possible.

What Is WordPress 7.1.3?

WordPress 7.1.3 is a maintenance and security release focused on improving the security, reliability, and stability of WordPress websites.

Unlike a major feature release, this update does not focus on introducing large new features. Instead, it addresses security vulnerabilities and fixes bugs discovered in WordPress core.

According to the official WordPress announcement, the release contains:

• 7 security fixes
• 4 bug fixes
• Security improvements across several WordPress core components
• Backported security fixes for supported older WordPress branches

Only the latest WordPress version is actively maintained, so keeping your website updated is an important part of WordPress security.

Why Should You Update to WordPress 7.1.3?

Security updates are particularly important because vulnerabilities in WordPress core can potentially affect websites running vulnerable versions.

WordPress 7.1.3 addresses several types of security issues, including cross-site scripting, SQL injection, unauthorized information disclosure, and permission-related issues.

The WordPress project specifically recommends updating websites immediately because this is a security release.

If your website is running WordPress 7.1 or an earlier version, checking for the latest available update should be a priority.

What Security Issues Were Fixed?

WordPress 7.1.3 includes fixes for several security issues reported by security researchers and the WordPress security team.

1. Stored Cross-Site Scripting in Comments

A stored XSS vulnerability affecting the Comments administration page was fixed. The issue could be triggered through pending comments.

This is particularly relevant for websites that accept comments or other user-generated content.

2. WordPress HTTP Denial-of-Service Issue

The release also fixes a denial-of-service issue involving the WP_Http::make_absolute_url() method.

This improvement helps strengthen WordPress’s HTTP handling.

3. Second-Order SQL Injection in WXR Export

Another important fix addresses a second-order SQL injection vulnerability in the WordPress WXR export functionality.

WXR export is used when WordPress content is exported, making this security improvement important for websites using WordPress’s built-in export tools.

4. Author Role Permission Issue

WordPress 7.1.3 fixes an issue that could allow users with the Author role to mark posts as sticky.

Sticky posts are normally controlled by users with higher-level permissions, so this update improves WordPress’s role and capability handling.

5. Unauthorized Comment Disclosure

A separate security issue could expose comments associated with private and unpublished posts to unauthenticated visitors.

The fix helps ensure that private content remains appropriately protected.

6. XSS Issue With Imgur Embeds

WordPress also addressed an XSS vulnerability involving Imgur embeds.

Websites that use embedded external media can benefit from keeping WordPress core updated so that security improvements are applied as they become available.

7. Forgeable Hook Parameters

The final listed security fix addresses forgeable parameters passed to the {status}_{type} hook, which could lead to action name collisions.

This further strengthens WordPress core’s handling of hooks and parameters.

WordPress 7.1.3 Also Includes Bug Fixes

In addition to security improvements, WordPress 7.1.3 includes 4 bug fixes.

Maintenance releases like this are important because they help improve the overall stability of WordPress without requiring website owners to wait for a major feature release.

For plugin and theme developers, keeping development environments updated can also help ensure compatibility testing is performed against the latest WordPress version.

How to Update to WordPress 7.1.3

Updating to WordPress 7.1.3 is straightforward.

From the WordPress Dashboard

Go to:

Dashboard → Updates → Update Now

If your website supports automatic background updates, WordPress may install the update automatically.

Before performing any WordPress core update, it is still a good practice to make sure your website has a recent backup.

What Should WordPress Plugin Developers Do?

WordPress plugin developers should also pay attention to maintenance and security releases.

After updating a development or staging website to WordPress 7.1.3, test important plugin functionality, especially features that interact with:

• User roles and permissions
• Comments
• Content export
• External embeds
• WordPress HTTP APIs
• Custom hooks
• User-generated content

For Gutenberg and block-based plugins, testing the plugin with the latest WordPress version is particularly useful for identifying compatibility problems before users encounter them.

WordPress 7.1.3 and Website Security

Keeping WordPress core, plugins, and themes updated is one of the simplest ways to improve website security.

However, updating WordPress alone is not enough. Website owners should also use trusted plugins and themes, keep administrator accounts secure, maintain regular backups, and remove unused software.

A secure WordPress website depends on maintaining the entire WordPress environment—not just WordPress core.
