WordPress 3.8.1, released in 2014, is an outdated version still used by 28 websites worldwide. This legacy version contains 22 known security vulnerabilities—including 1 critical flaw and 6 high-severity issues—that attackers actively exploit. If your website is running this version, you're at serious risk of data breaches, unauthorized access, and malware infections.

The most dangerous vulnerability is CVE-2023-2032, a critical SQL injection flaw in the Custom 404 Pro plugin that allows attackers to manipulate your database without permission. Other high-risk vulnerabilities enable privilege escalation, arbitrary file uploads, and authorization bypasses across multiple popular plugins.

This guide explains the threats targeting WordPress 3.8.1, how to check if you're vulnerable, and the exact steps to secure your installation immediately.

What is Wordpress 3.8.1?

WordPress 3.8.1 is an ancient version of WordPress, the world's most popular website platform. Released in 2014, it powered millions of websites but is now obsolete. Think of WordPress like the operating system for your website—it provides the core features you need to create, publish, and manage content without coding.

WordPress 3.8.1 specifically introduced the 'Maduro' theme and some UI improvements, but these features are now outdated and unsupported. More importantly, WordPress stopped releasing security updates for this version years ago. This means any new threats discovered (like the 22 vulnerabilities found today) will never be patched, leaving your site permanently exposed. Running WordPress 3.8.1 in 2025 is like driving a car without brakes—it might work, but disaster is inevitable.

Key Vulnerabilities in Wordpress 3.8.1

22 CVEs found. The most critical are explained below.

CRITICAL CVE-2023-2032 9.8/10 · CVSS v3.1 ⏱ Immediate
Custom 404 Pro Plugin - Database Attack Vulnerability

The Custom 404 Pro plugin has a serious flaw where it doesn't properly check user input before storing it in your database. Attackers can exploit this to inject malicious commands directly into your WordPress database. This is one of the most dangerous types of attacks because it can compromise your entire website.

Impact: Hackers could steal customer data, modify or delete website content, create unauthorized admin accounts, or take complete control of your WordPress site.

HIGH CVE-2025-3876 8.8/10 · CVSS v3.1 ⏱ Immediate
SMS Alert Plugin - User Permission Bypass Flaw

The SMS Alert Order Notifications plugin doesn't properly verify user identity when someone tries to log in. This means someone with low-level access could trick the system into acting like a higher-level user with more permissions. Even though attackers need some access to your site, they can escalate their privileges dangerously.

Impact: An attacker with basic access could gain admin-level permissions, allowing them to modify orders, access customer information, or make unauthorized changes to your store.

↗ View on NVD
HIGH CVE-2025-9561 8.8/10 · CVSS v3.1 ⏱ Immediate
AP Background Plugin - Unauthorized File Upload Risk

The AP Background plugin doesn't properly check who is uploading files or what type of files are being uploaded. Someone with subscriber-level access (a low-level account type) could upload dangerous files like executable programs or scripts to your server.

Impact: Attackers could upload malicious files that could be executed on your website, potentially giving them control over your server, stealing data, or spreading malware to your visitors.

↗ View on NVD
HIGH CVE-2020-36730 8.3/10 · CVSS v3.1 ⏱ Immediate
CMP Plugin - Public Access to Private Information

The CMP plugin doesn't verify that users have permission to access certain functions. This means anyone visiting your site—even without an account—could potentially view private posts, export sensitive data, or access administrative features.

Impact: Unauthorized visitors could read confidential posts, export your customer or business data, or disable important security features without any authentication needed.

↗ View on NVD
HIGH CVE-2013-1852 7.5/10 · CVSS v2 ⏱ Immediate
LeagueManager Plugin - Database Injection Vulnerability

The LeagueManager plugin has an old but serious vulnerability where attackers can inject malicious database commands through the league export page. Even though this is an older vulnerability, if you're still using this plugin version, your site remains exposed.

Impact: Hackers could execute unauthorized database commands, steal sensitive information, delete data, or compromise your website's integrity.

↗ View on NVD
HIGH CVE-2024-8757 7.2/10 · CVSS v3.1 ⏱ Within 7 days
WP Post Author Plugin - Database Query Injection Flaw

The WP Post Author plugin has a flaw where attackers can inject malicious code through a specific parameter. They can do this by timing how long the database takes to respond to carefully crafted requests, making it a slower but effective attack method.

Impact: Attackers could extract sensitive data from your database, including customer information, post details, or user credentials over time.

Frequently Asked Questions

Can I keep using WordPress 3.8.1 if I don't update?
No. WordPress 3.8.1 stopped receiving security updates in 2015. Every day you run this version, you're exposed to the 22 known vulnerabilities plus any new exploits discovered. Attackers use automated tools to target outdated WordPress versions, making your site an easy target. You must update to a supported version (6.4+) immediately.
Will updating WordPress 3.8.1 break my website?
Updating may break incompatible plugins or custom code, which is why backing up first is critical. However, staying on 3.8.1 is far riskier than updating. Modern WordPress versions are more stable and compatible than ever. Most sites update without issues, especially when you follow the steps in our fix guide and test on a staging environment first.
How long does it take to update from WordPress 3.8.1?
With proper backup and preparation, updating takes 15-30 minutes for most sites. The actual update process is automatic and takes less than a minute. Testing your site afterward (5-10 minutes) ensures nothing broke. The time investment is minimal compared to the risk of losing your entire website to a cyberattack.
What happens if my site gets hacked due to these CVEs?
Attackers could steal customer data, inject malware, redirect visitors to phishing sites, or hold your data for ransom. Recovery costs thousands and takes weeks, during which your reputation suffers and you lose revenue. Prevention (updating) costs nothing and takes minutes. Always choose prevention over recovery.
