How to Disable XML-RPC in WordPress for Better Security

WordPress is a powerful and flexible platform, but with its extensive features comes the need for robust security measures. One feature that often raises security concerns is XML-RPC. While XML-RPC can be useful for remote publishing or connecting to mobile apps, it’s also a common target for brute force attacks and other vulnerabilities. If you’re not using XML-RPC, disabling it can significantly improve your site’s security. In this post, we’ll explore what XML-RPC is, why you might want to disable it, and how to do so effectively—all while showing how enhancements like our Weblabs UI plugin can further empower your WooCommerce backend.

What Is XML-RPC in WordPress?

XML-RPC is a protocol that enables WordPress to communicate with external applications. It supports features such as remote publishing, integration with mobile apps, and pingbacks/trackbacks between blogs. However, these functionalities come at a price. XML-RPC can expose your site to risks including:

• Brute Force Attacks: Hackers may exploit XML-RPC to perform thousands of login attempts in a short period.
• DDoS Attacks: Exploitation via XML-RPC can lead to mass pingback requests that overwhelm your server.
• Exploitation of Vulnerabilities: Earlier XML-RPC implementations have known security flaws that attackers can target.

If your website doesn’t depend on XML-RPC, it’s wise to disable it to reduce your potential attack surface.

How to Disable XML-RPC in WordPress

There are several methods to disable XML-RPC, depending on your technical expertise and needs. We’ll cover three common approaches: using a plugin, adding custom code, and blocking XML-RPC via your server configuration.

Method 1: Disable XML-RPC Using a Plugin

For many users, the simplest way to disable XML-RPC is to use a dedicated plugin. Several plugins, such as Disable XML-RPC or comprehensive security solutions like Wordfence Security, offer an easy one-click approach.

Steps:

1. In your WordPress admin dashboard, navigate to Plugins > Add New.
2. Search for “Disable XML-RPC.”
3. Install and activate the plugin.
4. The plugin will automatically disable XML-RPC for your site.

This method is beginner-friendly and requires no coding knowledge.

Method 2: Disable XML-RPC with Custom Code

If you prefer a lightweight, code-based solution, you can disable XML-RPC by adding a small snippet to your site. This approach avoids the need for an additional plugin.

Steps:

1. Open your theme’s functions.php file, or use a plugin like Code Snippets to safely insert custom code.
2. Add the following code snippet:

<?php
// Disable XML-RPC in WordPress
add_filter( 'xmlrpc_enabled', '__return_false' );
?>

This code effectively disables XML-RPC across your site, cutting off external applications from accessing it.

Method 3: Block XML-RPC via .htaccess (For Apache Servers)

For those with server-level access, you can block XML-RPC requests using your .htaccess file. This method prevents your server from processing any requests to XML-RPC entirely.

Steps:

1. Access your site’s .htaccess file via FTP or your hosting control panel.
2. Add the following code:

# Block XML-RPC requests
<Files xmlrpc.php>
    Order Deny,Allow
    Deny from all
</Files>

3. Save and re-upload the file to your server.

This method reinforces your site’s security by preventing any XML-RPC requests from reaching your WordPress installation.

Verifying That XML-RPC Is Disabled

After implementing one of the methods above, it’s essential to verify that XML-RPC is indeed disabled.

If the tool reports that XML-RPC is disabled, you have successfully fortified your site against this common vulnerability.
