Vulnerable WordPress Plugin? Catch It Before It Becomes a Problem
Outdated plugins are one of the most common WordPress attack paths. The scanner matches your installed versions against a regularly updated database of known vulnerabilities so you can update, replace, or remove risky components.
A match means your site is running software with a publicly known flaw. Prefer updating first. If no patch exists, replace or remove the plugin or theme. Deactivated plugins can still be a risk if they remain on the server. For the July 2026 WordPress core wp2shell advisory, affected versions, fixed releases, and post-update checks, use our permanent security note.
Finding known vulnerabilities is step one. Pro adds email alerts, a faster vulnerability database refresh, plus Cloud Firewall, malware scanning, login protection, and 2FA while you patch.
Free vs Pro
Every site can check plugins, themes, and core for known issues. Upgrade when you want email warnings and the rest of the protection stack.
Forever free
A WordPress vulnerability scanner for every site - no license required.

Same scanner, plus alerts and the tools that protect you while you patch.
Most WordPress compromises start with outdated or abandoned plugins. The free scanner turns that into a clear checklist.
When a vulnerability is published and catalogued (often with a CVE ID from sources like the National Vulnerability Database), the scanner can flag matching versions on your site.
Software that never gets updates stays vulnerable forever. Security Ninja highlights known issues so you can update, replace, or remove before automated attacks find them.
Core gets security releases too. The scanner checks your WordPress version against known core issues so you are not relying on memory alone.

CVE stands for Common Vulnerabilities and Exposures. It is a public ID (for example CVE-2024-1234) that names a specific security flaw so researchers, tools, and site owners can talk about the same issue. Many WordPress plugin and theme vulnerabilities are assigned CVE IDs and listed in databases such as the National Vulnerability Database (NVD).
A WordPress vulnerability is a known weakness in WordPress core, a plugin, or a theme that attackers can exploit, for example to inject scripts, escalate privileges, or take over a site. Most documented WordPress vulnerabilities live in plugins. Updating or removing the affected software is the usual fix.
Yes. The WordPress vulnerability scanner is included in the free Security Ninja plugin for everyone, free and Pro installs. You can scan plugins, themes, and core without a paid license.
Security Ninja compares the versions of your installed plugins, themes, and WordPress core against a regularly updated database of known vulnerabilities. When your version matches a published issue, you see a clear warning in the dashboard so you can update, replace, or remove the software.
Yes. The scanner reviews installed plugins, themes, and WordPress core for known security issues and CVE matches.
Update to a fixed version when one is available. If there is no patch, replace the plugin or theme with a maintained alternative, or remove it. Do not ignore findings on deactivated plugins, unused files on the server can still be exploited.
No. It tells you which installed software has known issues so you can update, replace, or remove it promptly. Keeping WordPress, plugins, and themes updated remains essential.
A vulnerability scanner looks for known flaws in the software you already installed (CVEs and similar public advisories). A malware scanner looks for malicious or unexpected code in your files. Security Ninja includes vulnerability scanning for free; malware scanning is a Pro feature, and Core Scanner (also free) checks whether WordPress core files still match official originals.
No. Like other known-issue scanners, it only flags vulnerabilities after they are publicly documented and present in the vulnerability database. It cannot detect undisclosed zero-day flaws. Once an issue is published, a scan can alert you if your site is still running an affected version.
Scanning and dashboard results are free. Email alerts when vulnerabilities are detected are a Pro option. Free refreshes the vulnerability database weekly; Pro refreshes it daily.
Download Security Ninja for free CVE checks on plugins, themes, and core, or go Pro for email alerts, Cloud Firewall, malware scanning, and 2FA.
