Common WordPress Security Mistakes and How to Fix Them

WordPress is used by more than 40% of all websites globally, solidifying its position as a leading content management system. However, this popularity also paints a large target on its back. Many WordPress websites suffer from security breaches because of common mistakes users make that leave their sites vulnerable. If you’re a site owner, developer, or beginner trying to secure your site, this guide is designed to teach you how to fix common WordPress security issues step by step.

In this blog, we’ll uncover the most frequent WordPress security mistakes and their solutions, including common WordPress login security mistakes and how to prevent them. We’ll also cover manual techniques for resolving WordPress plugin vulnerabilities, how to safeguard your WordPress admin panel, and simple tricks like WordPress htaccess security tricks that don’t rely on plugins.

Why WordPress Sites Get Hacked Easily

Understanding why WordPress sites get hacked easily is key to preventing future attacks. Here’s why many WordPress sites become easy targets:

• Default admin username: Using “admin” or other predictable usernames makes it easier for attackers to guess login details.
• Weak or reused passwords: Simple passwords or passwords used across multiple sites can be cracked easily.
• Outdated WordPress core, themes, and plugins: Old versions often contain known vulnerabilities that hackers exploit.
• Unrestricted access to wp-admin and configuration files: Improperly secured admin areas and critical files allow hackers direct entry.
• No brute force protection: Without limiting login attempts, attackers can attempt thousands of password combinations.
• Poor file permission settings: Incorrect permissions allow unauthorised users to view or modify files.
• Insecure database setup: Default database prefixes or exposed database credentials increase risk.

By addressing these points, you can significantly reduce your risk of hacking and Secure Your WordPress Website against common threats.

Most Frequent WordPress Security Mistakes and Their Solutions

1. Using Weak Passwords and Default Admin Usernames

One of the most common pitfalls is fixing weak passwords and user roles in WordPress. Many users keep easy-to-guess passwords or default usernames like “admin,” which hackers can easily exploit.

Solution:

• Always use strong, complex passwords.
• Avoid using “admin” as a username; create a new administrator account and delete the old one.
• Enable two-factor authentication to enhance your account’s security.

2. Neglecting to Update WordPress Core, Themes, and Plugins

Outdated software often contains vulnerabilities. Hackers actively scan sites for known exploits.

Solution:

• Regularly update your WordPress core, themes, and plugins.
• Schedule a security audit WordPress site regularly to check for outdated components.
• Remove unnecessary plugins and themes to lower vulnerability exposure.

3. Ignoring File Permissions in WordPress

Incorrect file permissions in WordPress can allow unauthorised users to access or modify sensitive files, including your configuration files.

Solution:

• Ensure files and directories have the correct permissions—typically 644 for files and 755 for directories.
• Regularly check for and fix insecure file permissions in WordPress to ensure no unauthorised access.

4. No Brute Force Protection on Login Page

Brute force attacks involve trying multiple username-password combinations until the correct one is found. Many WordPress sites lack brute force protection.

Solution:

• Limit login attempts via plugins or manual methods.
• Use CAPTCHA or two-factor authentication.
• Implement IP blocking for suspicious login attempts.

5. Leaving the wp-config.php File Vulnerable

Your database credentials and encryption keys are located in the wp-config.php file. If compromised, your entire site is at risk.

Solution:

• Secure wp-config.php by moving it to a directory above the root or restricting its access using .htaccess rules.
• To prevent file editing from the WordPress dashboard, add define('DISALLOW_FILE_EDIT', true); to your wp-config.php file.

6. Ignoring WordPress Plugin Vulnerabilities

Many hacks happen through common plugin mistakes WordPress users make, such as installing plugins from untrusted sources or not updating them.

Solution:

• Only use trusted, reputable plugins.
• Regularly update plugins and remove unused ones.
• If issues persist, reach out to Plugin Developers to request patches or fixes directly.

7. No Protection on WordPress Admin Panel

The WordPress admin panel is the gateway to your site’s backend. Leaving it exposed invites attackers.

Solution:

• Implement recommended security measures to protect your WordPress admin dashboard.
• Protect your WordPress wp-admin directory with password protection or IP whitelisting.
• Use WordPress admin protection plugins or manual .htaccess rules to restrict access.

8. Ignoring XML-RPC Vulnerabilities

XML-RPC can be exploited to launch brute force or DDoS attacks.

Solution:

• Discover how to turn off XML-RPC in WordPress when it’s not required.
• If you require XML-RPC, protect it with security measures like limiting access or plugins that monitor its use.
