Keep everything updated: Promptly patch WordPress core, plugins, and themes to close known security vulnerabilities.
Use layered protection: Combine WAFs, MFA, backups, malware scanning, and restricted privileges instead of relying on one security tool.
Act quickly: Fast patching and continuous monitoring can significantly reduce the window attackers have to exploit vulnerabilities.
WordPress powers a huge share of websites, which also makes it a major target for cyberattacks. Security threats now extend far beyond simple spam or suspicious login attempts. Malware, remote code execution, malicious plugins, stolen accounts, and site hijacking can cause serious damage within a short time. The latest security data shows why regular protection matters. Patchstack reported 11,334 new WordPress ecosystem vulnerabilities in 2025, a 42% rise from 2024. Among them, 1,966, or 17%, had high severity.
An old WordPress version can leave a site open to known security flaws. Recent releases show how important fast updates have become. WordPress 7.0.2 fixed two serious flaws, including an SQL injection issue and a REST API batch-route issue that could lead to remote code execution. WordPress also advised immediate updates for affected sites.
WordPress 7.0.3 arrived on August 6, 2026, with several more security fixes. The release addressed pre-authentication reflected cross-site scripting on the login screen, server-side request forgery, CSS injection, an email-confirmation bypass, and other flaws. Regular core updates can close known entry points before attackers gain access.
Plugins and themes add useful features, yet each extra component can create another security risk. Patchstack recorded 11,334 new vulnerabilities across the WordPress ecosystem in 2025. The number marked a 42% increase from the previous year. High-severity flaws made up 1,966 cases, or 17% of the total.
This data makes plugin and theme updates a central part of site protection. A trusted developer may release a security fix soon after a flaw appears. Delayed updates leave that weakness open for a longer period.
Unused plugins can remain on a website long after their features stop serving a purpose. An old plugin may still contain a known flaw, even if no page uses its functions. A large WordPress ecosystem also means that developers may stop support for older products.
Removing unnecessary plugins reduces the number of components that need security checks. The same rule applies to unused themes. Keeping only essential software creates a smaller attack surface and makes security maintenance easier.
A secure WordPress site also needs strong account protection. Administrator accounts hold powerful permissions, so a stolen password can give an attacker control over important parts of a website.
Strong, unique passwords and multi-factor authentication can add another barrier. Admin access should also stay limited to people who need it. Old accounts should not remain active after their access ends.
A web application firewall, or WAF, can help block harmful requests before they reach WordPress. This layer can provide extra protection when a site faces a newly discovered vulnerability.
The 2026 WP2Shell incident shows the value of this extra defence. Wiz reported that 60% of organizations with WordPress had at least one vulnerable instance at first. It also found that 25% had a vulnerable server exposed to the Internet. Within 24 hours, those figures fell to 50% and 10% after organizations took protective action.
A backup can turn a serious security incident into a manageable recovery task. Malware or a hijacked account can damage files, pages, databases, and settings. A clean backup gives the site a known-good version for restoration.
Backups should exist outside the main website environment. Several restore points can also help when the latest copy contains an infection. A backup has value only when the restore process works, so regular recovery tests matter.

Malware can hide inside files, plugins, themes, databases, or administrator accounts. A regular security scan can help detect suspicious changes before they cause wider damage.
Current WordPress vulnerability data includes exploited flaws with CVSS scores as high as 10.0. Some involve arbitrary file uploads, which can provide a path for harmful files to reach a server. Regular scans can help identify signs of compromise and support faster cleanup.
Plugin upload access deserves special attention. Attackers may try to gain administrative privileges and then use legitimate WordPress features to place harmful code on a site.
Wiz researchers found that attackers used the WP2Shell vulnerability chain to reach remote code execution and upload malicious plugins that created persistent backdoors. Restricting administrator privileges and plugin installation rights can reduce this risk.
WordPress security does not stop at the dashboard. The hosting environment also needs protection. Exposed services, weak server credentials, poor access controls, and outdated software can create additional routes into a website.
The WP2Shell figures show the scale of this issue. At first, 25% of organizations had a vulnerable WordPress server exposed to the Internet. After 24 hours, that figure dropped to 10%. Fast patching and tighter server controls can sharply reduce exposure.
WordPress security changes throughout the year, so a fixed annual security check is not enough. Security advisories can reveal new flaws and provide details about available fixes.
The release history from 2026 makes this clear. WordPress 6.9.2 addressed 10 security issues in March, while later releases added further fixes. WordPress 7.0.2 and 7.0.3 also addressed serious vulnerabilities within the same year.

A secure WordPress website needs several layers rather than one security product. Current figures show a fast-growing vulnerability landscape, while real attacks show how quickly exposed systems can become compromised. Core updates, plugin maintenance, account protection, WAF rules, backups, malware scans, restricted access, server hardening, and security alerts can work together as a practical defence.
The key lesson from the latest data is simple: speed matters. WP2Shell showed a major reduction in vulnerable exposure within just 24 hours after organizations took action. Regular security checks can therefore do more than fix old problems. They can reduce the window that attackers have to exploit a newly exposed weakness.
1. How often should I update WordPress?
Update WordPress core, plugins, and themes as soon as security updates become available, especially when a vulnerability is actively being exploited.
2. Are unused WordPress plugins a security risk?
Yes. Unused or abandoned plugins can contain vulnerabilities and increase your site's attack surface. Remove plugins and themes you no longer need.
3. Does a WAF completely protect a WordPress website?
No. A WAF adds an important security layer, but it should work alongside updates, strong authentication, backups, malware scanning, and server security.
4. Why are WordPress backups important for security?
Backups provide a clean recovery point if malware, unauthorized access, or site hijacking damages your website. Test restores regularly to ensure backups actually work.
5. What is the best way to prevent WordPress site hijacking?
Use layered security: keep software patched, protect administrator accounts with MFA, restrict privileges, scan for malware, secure hosting access, maintain reliable backups, and follow security advisories.
