Disable XML-RPC in WordPress with WPMasterToolKit
WordPress' XML-RPC protocol enables external applications to communicate with your site, for example to publish content via tools such as the WordPress mobile app. However, this functionality is rarely used on most modern sites, and represents a potential security risk. With the Disable XML-RPC from WPMasterToolKit, you can easily disable this feature and strengthen your site's security.
Why disable XML-RPC?
Although XML-RPC was useful in the past, it is now often replaced by the WordPress REST API. Here are a few reasons why you might want to disable XML-RPC:
- Reduce brute-force attacks XML-RPC: XML-RPC can be exploited by attackers to carry out massive login attempts, as it allows multiple passwords to be tested in a single request.
- Protection against abuse Some vulnerabilities exploit XML-RPC to send pings or malicious requests, which can slow down your site or make it vulnerable.
- Obsolete functionality : Most sites no longer use XML-RPC, especially since the introduction of the REST API in WordPress.
- Simplified safety By completely disabling XML-RPC, you reduce your site's attack surface, making it easier to manage overall security.
How the Disable XML-RPC module works
The module Disable XML-RPC completely disables XML-RPC on your WordPress site. Here's how it works:
Disabling XML-RPC
- The module uses the
xmlrpc_enabled
to disable XML-RPC at source. This prevents all XML-RPC requests from being processed by WordPress.
Redirecting requests to a 403 error
- Any attempt to access XML-RPC (
xmlrpc.php
) is immediately blocked with an HTTP 403 (Forbidden) response. This deters attackers and prevents misuse of this feature.
Minimalist, secure solution
- The module integrates directly with native WordPress filters, guaranteeing a lightweight, reliable method of disabling XML-RPC without affecting other site functionality.
How to use this module
- Installation : Install and activate the plugin WPMasterToolKit on your WordPress site.
- Module activation Go to the list of modules and activate "Disable XML-RPC".
- Automation Once activated, the module immediately disables XML-RPC and blocks all associated requests.
