WordPress powers over 40% of all websites on the internet, making it a prime target for cybercriminals. One of the most common attack vectors? User enumeration – a technique hackers use to discover valid usernames on your WordPress site.
As someone who’s spent years working in cybersecurity, I’ve seen countless WordPress sites compromised through user enumeration attacks. That’s why I developed a free WordPress User Enumeration Checker at tools.hueston.co that helps website owners identify and fix these vulnerabilities before attackers can exploit them.
What is WordPress User Enumeration?
WordPress user enumeration is a reconnaissance technique where attackers attempt to discover valid usernames on a WordPress website. Once they have a list of valid usernames, they can launch targeted brute force attacks, dramatically increasing their chances of gaining unauthorized access to your site.
Common enumeration methods include:
- REST API endpoints (/wp-json/wp/v2/users)
- Author archives (/?author=1)
- Login error messages
- RSS feeds and XML-RPC endpoints
- Oembed functionality
Why Should You Care About User Enumeration?
User enumeration might seem harmless, but it’s actually the first step in many successful WordPress attacks. Here’s why it’s dangerous:
Enables Targeted Attacks: Instead of randomly guessing usernames, attackers can focus their efforts on known valid accounts, making brute force attacks significantly more effective.
Reveals Site Structure: User enumeration can expose information about your site’s administrative structure, user roles, and posting patterns.
Compliance Issues: Many security standards and regulations require websites to protect user information, including usernames.
SEO Impact: Sites that get compromised often suffer from malware infections, blacklisting, and ranking penalties.
Introducing a Free Solution for WordPress Security
Frustrated by the lack of accessible security tools for WordPress site owners, I created a comprehensive WordPress User Enumeration Checker that’s completely free to use. This tool, available at tools.hueston.co, simulates the same techniques that real attackers use, giving you an accurate picture of your site’s vulnerability to user enumeration attacks.

- Risk level assessment
Step 4: Take Action
Based on the results, you’ll receive specific recommendations for securing your site against user enumeration attacks.
Common Vulnerabilities Our Tool Detects
REST API User Enumeration
WordPress REST API endpoints like /wp-json/wp/v2/users can expose user information. The tool checks if these endpoints are accessible and what information they reveal.
Author Archive Enumeration
Many WordPress sites allow user enumeration through author archives (e.g., yoursite.com/?author=1). The scanner tests these endpoints systematically.
Login Error Messages
Verbose login error messages can reveal whether a username exists. The tool analyzes your login form responses to identify information leakage.
RSS and Feed Enumeration
WordPress feeds often contain author information that can be exploited for enumeration. The scanner checks these potential information sources.
How to Fix WordPress User Enumeration Vulnerabilities
If the tool discovers vulnerabilities, don’t panic! Here are proven methods to secure your WordPress site:
Method 1: Disable REST API User Endpoints
Add this code to your theme’s functions.php file:
php
// Disable REST API user endpoints
add_filter(‘rest_endpoints’, function($endpoints) {
if (isset($endpoints[‘/wp/v2/users’])) {
unset($endpoints[‘/wp/v2/users’]);
}
if (isset($endpoints[‘/wp/v2/users/(?P<id>[\d]+)’])) {
unset($endpoints[‘/wp/v2/users/(?P<id>[\d]+)’]);
}
return $endpoints;
});
Method 2: Block Author Archive Access
Redirect author archives to prevent enumeration:
php
// Redirect author archives
add_action(‘template_redirect’, function() {
if (is_author()) {
wp_redirect(home_url());
exit;
}
});
Method 3: Use Security Plugins
Install reputable security plugins like:
- Wordfence Security
- iThemes Security
- All In One WP Security
Method 4: Implement Rate Limiting
Limit the number of requests from a single IP address to prevent automated enumeration attempts.
Best Practices for WordPress Security
Beyond fixing user enumeration vulnerabilities, follow these security best practices:
Strong Username Practices: Avoid common usernames like “admin,” “administrator,” or your site name. Use unique, non-predictable usernames.
Regular Updates: Keep WordPress core, themes, and plugins updated to the latest versions.
Strong Passwords: Use complex passwords and consider implementing two-factor authentication.
Regular Backups: Maintain regular, tested backups of your website.
Security Monitoring: Regularly scan your site for vulnerabilities using tools like ours.
