7 Security Vulnerabilities Fixed in WordPress 7.1.3

1. Stored XSS in WordPress Comments

A stored cross-site scripting (XSS) vulnerability affected the Comments administration page.

Malicious content in pending comments could potentially execute unwanted JavaScript when an authorized moderator interacted with it under certain conditions.

The issue was reported by Trail of Bits in collaboration with OpenAI.

2. Denial-of-Service Vulnerability

Researchers discovered a denial-of-service (DoS) weakness in the WP_Http::make_absolute_url() method.

Under specific conditions, the issue could cause excessive processing and affect website availability.

Anthropic reported the vulnerability.

3. SQL Injection in WXR Export

WordPress also fixed a second-order SQL injection issue involving its WXR export functionality.

The vulnerability concerned how certain previously stored data was handled during export operations.

This issue was reported by Anthropic.

4. Unauthorized Sticky Posts

Another security weakness allowed users with the Author role to mark posts as sticky without the necessary permissions.

WordPress 7.1.3 corrects this authorization problem.

The issue was also reported by Anthropic.

5. Private Comment Information Disclosure

A vulnerability could expose comments associated with private or unpublished posts to unauthenticated visitors.

Although the issue involved comment data rather than unrestricted access to private posts, it represented a significant privacy concern.

Ananda Dhakal from Patchstack reported this vulnerability.

6. XSS Through Imgur Embeds

WordPress fixed a cross-site scripting weakness affecting embedded Imgur content.

The issue involved how externally supplied embed content was trusted and displayed.

The security fix improves handling of potentially unsafe embedded content.

7. WordPress Hook Name Collision

The final security issue involved forgeable parameters passed to dynamic WordPress hooks.

Under certain conditions, these parameters could cause action name collisions and unintended behavior.

Alex Concha from the WordPress security team reported the issue.

Four Maintenance Fixes in WordPress 7.1.3

Alongside the seven security patches, WordPress confirmed four maintenance fixes.

Technical reporting identifies improvements involving:

  • Media uploads: Preventing fatal errors on servers without the optional PHP DOM extension.
  • Admin toolbar: Correcting oversized site icon display.
  • ReverbNation embeds: Addressing an outdated embed endpoint.
  • Someecards embeds: Removing an unsupported embed provider.

These maintenance changes help improve compatibility and everyday website functionality.

How to Update WordPress 7.1.3 Safely

Updating WordPress is straightforward, but preparation helps prevent unexpected problems.

Step 1: Back Up Your Website

Create a complete backup of your WordPress database and files.

Use a trusted backup plugin or your hosting provider’s backup system.

Step 2: Check Plugin Compatibility

Review important plugins, including WooCommerce, Elementor, payment gateways, and security extensions.

Check your theme’s compatibility information as well.

Step 3: Test on a Staging Website

For business-critical websites, install the update on a staging copy first.

Test important pages, contact forms, checkout functionality, and user accounts.

Step 4: Install WordPress 7.1.3

Open your WordPress dashboard and navigate to:

Dashboard → Updates → Update Now

If automatic background updates are enabled, WordPress may already have installed the release.

Step 5: Clear Website Cache

Clear your WordPress cache, server cache, and CDN cache if applicable.

This helps ensure visitors receive updated content and resources.

Step 6: Test Your Website

Check your homepage, navigation, login page, media uploads, forms, and checkout.

Also confirm that your plugins and theme continue working normally.

What About Older WordPress Versions?

WordPress is backporting the security fixes to older eligible branches, including versions as far back as WordPress 4.7.

However, only the newest WordPress version receives active support.

For most websites, upgrading to the current supported release is the safer long-term approach.
