WordPress powers over 43% of all websites on the internet, making wordpress security not just a buzzword, but a critical concern for millions of site owners worldwide. Imagine waking up one morning to find your carefully crafted blog or e‑commerce store defaced, or worse, distributing malware. I’ve been there—late nights spent scrambling to restore backups after a plugin flaw was exploited taught me the hard way that prevention truly is better than cure.
In this post, we’ll dive beneath the surface of the most common WordPress vulnerabilities, compare how different threat vectors stack up against each other, and share actionable solutions to lock down your site once and for all.
Comparison: Vulnerabilities Then vs. Now
| Category | 2023 (Patchstack Data) | 2024 (Wordfence Data) |
|---|---|---|
| Total New Vulnerabilities | 5,948 in plugins & themes (24% ↑ from 2022) Patchstack | 68% ↑ from 2023 disclosures; 81% medium‑severity Wordfence |
| Core vs. Plugins vs. Themes | Core: 0.2% Plugins: 97% Themes: 3% Patchstack | Plugins: 96% Themes: 4% Core:<0.1% Wordfence |
| High‑Threat Issues | 15.7% unpatched/abandoned; 42.9% high/critical severity theadminbar.com | 7.4% high‑threat (149% ↑ vs. 2023); Arbitrary file uploads most common Wordfence |
| Unpatched Rate | 15.7% vulnerabilities still open in 2024 Patchstack | 35% remain unpatched in 2025 Wordfence |
| Attack Volume | 159 billion credential‑stuffing blocks in 2022 White Canvas | 54 billion malicious requests blocked; 55 billion password attacks blocked in 2024 Wordfence |
Key Insights & Solutions
1. Outdated Plugins & Themes
Insight: Plugins and themes are the Achilles’ heel—over 96% of new vulnerabilities stem from them rather than WordPress core Wordfence.
Solution:
- Regular Updates: Always update within 48 hours of a security patch
- Reputable Sources: Stick to plugins with large install counts and active maintenance
- Abandonment Audit: Remove or replace plugins not updated in 6+ months
2. Brute Force & Credential‑Stuffing Attacks
Insight: Automated bots attempt billions of logins yearly. Wordfence alone blocked 55 billion password attacks in 2024 Wordfence.
Solution:
- Limit Login Attempts: Lock out IPs after 5 failed tries
- Strong Passwords: Enforce length (12+ chars), complexity, and passphrase use
- Two‑Factor Authentication (2FA): Add an extra layer via TOTP or SMS
3. SQL Injection & Cross‑Site Scripting (XSS)
Insight: XSS remains the #1 vulnerability type (46% of disclosures), followed by SQL injection Wordfence.
Solution:
- Input Sanitization: Use WordPress functions (
esc_html(),prepare()) instead of raw queries - Content Security Policy: Block inline scripts and restrict external sources
- WAF (Web Application Firewall): Deploy services like Sucuri or Cloudflare WAF
4. Insecure Hosting & File Permissions
Insight: Misconfigured servers can expose sensitive files; insecure hosting magnifies risk.
Solution:
- Secure Hosting Provider: Choose managed WordPress hosts with proactive security (e.g., Hostinger, Kinsta, WP Engine).
- File Permissions: Set
wp-config.phpto400and directories to755at minimum - SSH/SFTP Only: Disable FTP in favor of encrypted connections
5. Backup & Recovery
Insight: 35% of disclosed vulnerabilities remain unpatched—routine backups are your safety net Wordfence.
Solution:
- Automated Backups: Daily snapshots to off‑site storage (e.g., Amazon S3, Google Drive)
- Test Restores: Quarterly drills to verify backup integrity
- Versioned Backups: Keep at least 30 days of history
