WordPress Security 101: Common Issues & Fixes

Hey there, WordPress wizards! It’s great to see you back! We’re ready to dive deeper into the nitty-gritty of WordPress security, presenting a hefty list of neatly categorized common issues, tailored just for you. Whether you’re a seasoned WordPress pro or a fresh-faced newbie, this guide will be your trusty compass through the sometimes stormy seas of website security. So, grab your coffee, get comfy, and let’s jump right in!

Unauthorized Access

  • Brute Force Attacks: Hey, it’s like a guessing game, but not fun. Hackers try to guess your password to sneak in. The fix? Use strong, unique passwords and limit login attempts.
  • Phishing Attacks: It’s a trick! Hackers fool you into giving them your login details. Always double-check URLs and email senders.
  • Privilege Escalation: Some users get more power than they should. Keep an eye on user roles and capabilities.
  • Weak Passwords: You know what’s not cool? Simple passwords. They’re like an open invitation for hackers. So, encourage users to mix it up with complex passwords and change them regularly.
  • Unprotected Access Points: Imagine leaving your house door open. That’s what unprotected APIs and access points are like. So, let’s lock those doors with authentication and authorization.

Code Injections

  • SQL Injections: Hackers try to mess with your database using nasty, malicious SQL code. The best defense? Keep your WordPress version, themes, and plugins fresh and updated.
  • Cross-Site Scripting (XSS): Hackers slip malicious scripts into your pages. To stop this, make sure to validate, sanitize, and escape user inputs. WordPress has got your back with several functions for this.
  • Cross-Site Request Forgery (CSRF): Hackers trick users into doing things they didn’t mean to. Use nonces in your forms to prevent this.
  • Object Injections: Hackers can exploit PHP’s unserialize function to sneak in harmful code. It’s like a secret backdoor. So, let’s close it by disabling PHP object injection where possible.
  • Local File Inclusion (LFI): This is when hackers trick WordPress into running files on your server. It’s like inviting a vampire into your house. So, let’s keep them out by validating user input and restricting file permissions.


  • Backdoors: Hackers find hidden ways into your site. Regularly scan your site for any files that seem out of place.
  • Drive-by Downloads: Users might unintentionally download malware simply by visiting your site. To prevent this, ensure all software is up-to-date and utilize a WordPress security plugin for enhanced protection. Many of these plugins come with a Web Application Firewall (WAF).
  • Malicious Redirects: Users can be redirected to harmful sites. Make sure to check your .htaccess file for any suspicious redirects.
  • File Inclusion Exploits: Hackers exploit vulnerabilities in PHP’s include and require statements. It’s like they’re sneaking in through the window. Keep your PHP version up-to-date to keep them out.
  • Distributed Denial of Service (DDoS): Imagine a crowd blocking your shop entrance. That’s a DDoS attack. Use a CDN or other DDoS prevention service to keep the crowd under control.

Hosting Environment

  • Insecure Server Configuration: Hackers exploit server vulnerabilities. Choose a reputable host and keep server software up-to-date.
  • Outdated PHP Version: Older versions of PHP might have vulnerabilities (weak spots), like a rusty lock. To keep your site secure, always use the latest supported PHP version.
  • Shared Hosting Vulnerabilities: It’s like living in a shared house. If one person gets sick, everyone could get sick. Consider using a dedicated server or VPS to stay healthy.
  • Insecure File Permissions: It’s like leaving your diary open for anyone to read. Set correct file permissions (644 for files, 755 for directories) to keep your secrets safe.
  • Unsecured FTP: It’s like leaving your house keys under the doormat. Hackers can easily find them and gain access. So, switch to SFTP or SSH to keep your keys safe.


  • Spam Comments: Your site gets flooded with unwanted comments. Use an anti-spam plugin and enable comment moderation.
  • Hotlinking: Others use your images on their site, eating up your bandwidth. Prevent hotlinking with .htaccess rules to keep your bandwidth for yourself.
  • Unwanted Trackbacks/Pingbacks: Your site gets linked to spammy sites. Disable trackbacks and pingbacks.
  • Exposed WordPress Version: Your WordPress version is visible, making it easier for hackers to find vulnerabilities. It’s like wearing a sign that says “I’m vulnerable”. Hide your WordPress version to keep hackers guessing.
  • Outdated Themes and Plugins: It’s like using an old lock that’s easy to pick. Hackers can exploit known vulnerabilities. So, keep your themes and plugins updated to stay secure.

And there you have it, folks! We’ve walked through a comprehensive list of common WordPress security issues and their solutions. It might seem overwhelming, but remember, every epic journey starts with a single step. A sprinkle of regular maintenance and a dash of vigilance can secure your site in no time. So, don’t be intimidated. You’ve totally got this! Keep exploring, keep learning, and above all, keep creating. After all, the digital world is your playground.
