If you’re running a WordPress site, here’s a troubling statistic: nearly 30% of WordPress plugin vulnerabilities never receive a security update. That means millions of websites are sitting ducks for cyberattacks, all because of neglected software flaws.
A recent report specializing in WordPress security found that in 2021 alone, reported vulnerabilities shot up by 150% compared to the previous year. That’s a staggering increase, and considering WordPress is the world’s most widely used content management system (CMS), this issue isn’t just a niche concern—it’s a ticking time bomb for website administrators everywhere.
Where Do the Risks Lie?
According to experts at Patchstack, the vast majority of WordPress vulnerabilities don’t come from the core platform itself. In fact, only 0.58% of reported flaws in 2021 were found in WordPress core files. The real problem? Plugins and themes, which are created by third-party developers and vary widely in quality and security practices.
Breaking it down further, a whopping 92% of these vulnerabilities were found in free plugins, while premium (paid) plugins accounted for just 8.6% of reported issues. That means site owners relying on free tools may be exposing themselves to significantly greater risk.
Critical Vulnerabilities and Widespread Impact
Among the vulnerabilities identified last year, five severe flaws were found across 55 different WordPress themes. Most of these stemmed from improper file upload handling—an issue that can allow attackers to sneak malicious files onto a website with devastating consequences.
When it comes to plugins, the numbers are even more alarming. Researchers discovered 35 critical vulnerabilities, including two that may have compromised up to 4 million websites. Some of the most high-profile security risks were found in widely used plugins like OptinMonster, which is active on roughly 1 million sites, and the All in One SEO plugin, which boasts over 3 million active installations. While the most urgent flaws in these plugins were patched, other plugins with millions of users never received a single update to address severe security holes.
The Most Common WordPress Plugin Security Issues
Security experts have identified the biggest offenders when it comes to WordPress plugin vulnerabilities. At the top of the list? Cross-site scripting (XSS), which allows attackers to inject malicious code into web pages. Other frequently reported issues include request spoofing, SQL injection (a favorite technique for stealing database information), and unauthorized file uploads.
What Can Website Owners Do?
Faced with these risks, WordPress site administrators must take security into their own hands. Here are a few key steps to protect your website:
- Opt for paid plugins when possible. Developers of premium plugins typically offer better support and more frequent security updates.
- Minimize the number of plugins installed. The fewer third-party tools you rely on, the smaller your attack surface.
- Keep everything updated. Regularly update plugins, themes, and the WordPress core to the latest versions to patch known vulnerabilities.
Cyber threats aren’t going away, and WordPress remains a prime target. Staying vigilant and proactive with updates and security best practices is the best way to keep your website safe from attack.
