WordPress Security 2026: Leaks, backdoors and why maintenance is crucial

WordPress is the world's most widely used content management system - which is precisely why it is a favourite target for attackers. The biggest vulnerability is not in the core system itself, but in plugins.

Current figures show: Around 96% of all security vulnerabilities are caused by plugins. At the same time, the number of vulnerabilities continues to rise - over 11,000 new vulnerabilities were discovered in the WordPress ecosystem in 2025 alone.

Current examples: How real the danger is

The threat is not theoretical - it happens every day:

• A critical vulnerability in the «User Registration & Membership» plugin allowed attackers to create hidden administrator accounts and take over entire websites 
• In another case, legitimate plugins were taken over and fitted with backdoors that compromised thousands of websites
• Vulnerabilities such as remote code execution even allow attackers to execute arbitrary malicious code directly on the server
  
  

In addition, over 100 new vulnerabilities in plugins are published every week - many of which are actively exploited, often automatically.

The real problem: outdated systems

Most attacks do not utilise complex zero-day exploits, but rather known loopholes that have long since been closed.

The crucial point:
Most security problems are caused by a lack of updates and maintenance

Plugins, themes and even WordPress itself need to be updated regularly. If this is not done, known backdoors remain open - often for weeks or months.

Why regular maintenance is essential

A secure WordPress instance requires more than just a one-off setup. It is crucial:

• Ongoing updates of plugins, themes and core
• Safety checks and monitoring
• Removal of unsafe or outdated extensions
• Regular backups for emergencies

Without these measures, the risk of a successful attack increases dramatically.
