How to Determine Whether Your Website Uses XML-RPC (Part 2)

Before disabling XML-RPC, take a few minutes to determine whether your website actually depends on it. Many administrators disable the feature without checking for existing integrations, only to discover later that a third-party application or automation script has stopped working.

How to Determine Whether Your Website Uses XML-RPC

The easiest place to start is by reviewing the applications you actively use to manage your website. Ask yourself a few simple questions. Do you publish articles exclusively through the WordPress dashboard? Do you use the official WordPress mobile application? Have you connected any legacy desktop publishing software? Are there custom scripts or older automation tools interacting with your site?

If the answer to all of these questions is no, there is a good chance XML-RPC is no longer necessary.

You can also inspect your web server logs for requests targeting xmlrpc.php. Occasional requests from search engines or automated bots are perfectly normal and do not indicate legitimate usage. What you are looking for are successful requests originating from applications you recognize. If your logs show only failed login attempts, automated scans, or suspicious traffic, disabling XML-RPC is unlikely to affect normal website operation.

Website owners using managed WordPress hosting can often request this information directly from their hosting provider. Many hosts maintain detailed logs and can quickly determine whether legitimate XML-RPC requests have been received recently.

Performing this simple audit helps avoid unnecessary troubleshooting later and ensures your decision is based on evidence rather than assumptions.

Recognizing Suspicious XML-RPC Activity

Because XML-RPC is publicly accessible by default, it attracts a constant stream of automated scans from bots across the internet. Seeing requests to xmlrpc.php in your logs is not unusual. The important task is distinguishing harmless background noise from genuine attack attempts.

A typical scan consists of a single request checking whether the endpoint exists. Security scanners, uptime monitoring services, and vulnerability assessment tools frequently perform these checks. These isolated requests generally pose little risk.

More concerning patterns include hundreds or thousands of repeated requests within a short period, particularly when they originate from multiple IP addresses around the world. Attackers often rotate IP addresses to avoid detection while attempting password guessing or probing for vulnerable configurations.

Another warning sign is a high number of HTTP POST requests directed at xmlrpc.php. Since XML-RPC accepts POST requests, sustained POST activity may indicate an automated attack rather than normal website usage.

Administrators should also monitor server performance during these events. Sudden increases in CPU usage, PHP workers, memory consumption, or database activity may suggest that XML-RPC requests are placing unnecessary load on the server.

Modern firewall solutions make identifying these patterns much easier by grouping similar requests and automatically flagging suspicious behavior. Reviewing security reports regularly helps ensure that unusual activity is detected before it develops into a more serious problem.

XML-RPC and Modern WordPress Security

The WordPress ecosystem has changed dramatically over the past decade. Security today extends far beyond simply enabling or disabling XML-RPC. Modern websites benefit from multiple layers of protection that work together to prevent attacks long before they reach WordPress itself.

For example, many hosting providers automatically filter malicious traffic at the network level. Web application firewalls analyze incoming requests in real time, blocking suspicious patterns before PHP even begins processing them. Rate limiting prevents attackers from overwhelming authentication systems, while bot management services identify automated traffic based on behavioral analysis rather than simple IP addresses.

These advancements mean that XML-RPC is no longer the single point of concern it once was. A website protected by strong passwords, two-factor authentication, updated software, managed hosting, and a reputable firewall is significantly more secure than a website relying solely on disabling XML-RPC.

Security should always be viewed as a layered strategy rather than a single setting. Removing unnecessary services certainly contributes to overall protection, but it should complement not replace good maintenance practices.

Regular updates, secure backups, malware scanning, principle-of-least-privilege user accounts, and continuous monitoring remain essential regardless of whether XML-RPC is enabled.

Common Misconceptions About XML-RPC

One of the biggest myths surrounding XML-RPC is that simply disabling it will make a WordPress website completely secure. Unfortunately, cybersecurity is never that simple.

Attackers continuously adapt their methods. If XML-RPC is unavailable, they may simply target the standard login page, vulnerable plugins, outdated themes, insecure file permissions, or exposed administrative interfaces instead. Removing one potential entry point does not eliminate every possible threat.

Another misconception is that XML-RPC itself contains malware or acts as a backdoor. This is incorrect. XML-RPC is an official component of WordPress developed to provide legitimate remote communication. The protocol does exactly what it was designed to do. Problems arise only when malicious users abuse its capabilities.

Some website owners also believe that every plugin requires XML-RPC. In reality, the overwhelming majority of modern plugins communicate through the WordPress REST API or other secure integration methods. Very few actively maintained plugins depend exclusively on XML-RPC today.

Finally, there is a belief that disabling XML-RPC improves website speed. Under normal conditions, the performance difference is negligible. The primary advantage comes from preventing unnecessary automated requests rather than making WordPress itself faster.

Understanding these misconceptions helps administrators make balanced decisions based on technical facts rather than internet rumors.

A Practical Decision Framework

If you are still uncertain about what to do, a simple decision framework can help.

Keep XML-RPC enabled if:

• You actively use legacy publishing software.
• Your business relies on older integrations that have not yet migrated to the REST API.
• Internal applications communicate with WordPress through XML-RPC.
• Testing confirms that disabling it would interrupt critical workflows.

Consider disabling XML-RPC if:

• You manage your website exclusively through the WordPress dashboard.
• Your plugins and services use the REST API.
• Server logs show only automated scans or failed attacks.
• You want to reduce unnecessary public endpoints as part of a broader security strategy.

This approach avoids unnecessary risk while ensuring that important functionality remains intact. Rather than treating XML-RPC as either completely safe or completely dangerous, evaluate it based on your own website’s requirements.
