WordPress Website Vulnerability Scanner
Scan your WordPress site for plugin CVEs, theme vulnerabilities, core version exposure, XML-RPC misuse, and more. Free, instant graded report — no installation required.
WordPress is the world's most popular content management system, powering more than 43% of all websites as of 2026. That dominance makes it the most heavily targeted platform by automated attack tools. The WordPress vulnerability landscape is shaped primarily by its plugin ecosystem: with over 60,000 plugins in the official repository, and thousands more distributed directly by developers, a single security flaw in a popular plugin can expose millions of sites to attack simultaneously.
Running a regular WordPress website vulnerability assessment is not optional for sites that handle user data, payments, or sensitive content — it is a baseline security hygiene requirement. This page explains the most common WordPress-specific risks, how to scan for them using both Vuln0x and open source tools like WPScan, and what a hardened WordPress configuration looks like in 2026.
For a broader view of scanning options, see our Website Vulnerability Scanner overview and the Best Website Vulnerability Scanner Tools in 2026 guide.
Top WordPress Security Risks in 2026
Vulnerable plugins
Plugins account for the majority of WordPress CVEs. Attackers regularly target popular plugins with large install bases — a single unpatched plugin on millions of sites creates an enormous attack surface. Vuln0x cross-references installed plugin versions against known vulnerability databases and flags any plugin with a public CVE that has not been patched.
Outdated themes
Themes run PHP code with the same privileges as core WordPress files. Vulnerabilities in theme template files — particularly custom page templates that accept GET or POST parameters — can lead to XSS, PHP object injection, or file inclusion. Keeping themes updated and removing unused themes reduces your attack surface significantly.
WordPress core exposure
The WordPress version is often exposed in the page source via generator meta tags, login page styling, and the readme.html file in the web root. Attackers use version fingerprinting to select applicable exploits before launching targeted attacks. Vuln0x detects version exposure and checks whether the identified version has any known critical vulnerabilities.
XML-RPC exposure
The xmlrpc.php endpoint enables remote management features that most WordPress sites do not need. When enabled, it can be abused for credential brute-forcing (amplified by the multicall method), DDoS amplification, and in older WordPress versions, unauthenticated file uploads. Disabling or restricting XML-RPC is one of the highest-impact configuration changes you can make.
User enumeration
WordPress's default routing exposes a list of registered usernames via the author URL parameter (?author=1, ?author=2, etc.) and the WP REST API (/wp-json/wp/v2/users). Once attackers have a valid username, credential-stuffing and brute-force attacks become significantly more effective. Vuln0x checks whether user enumeration is possible on your site.
Exposed files and directories
Debug logs (debug.log), backup files (.sql, .zip, .tar.gz in the web root), exposed wp-config.php, and directory listing on uploads or plugin directories are common findings on WordPress sites. These exposures can leak database credentials, secret keys, and personal data. Vuln0x probes for these exposures automatically.
How to scan a WordPress site for vulnerabilities
Using Vuln0x (no install)
The fastest way to run a WordPress website vulnerability assessment is to use the scan widget on this page. Enter your WordPress site URL and Vuln0x will immediately begin a passive surface check, returning a security grade and findings within seconds. Register for a free account to unlock the full scan, which includes WordPress-specific checks against the plugin and theme vulnerability database, XML-RPC exposure probes, and user enumeration tests.
Using WPScan (CLI)
WPScan is the most widely used open source WordPress-specific scanner. Install it via RubyGems (gem install wpscan) or use the official Docker image. A basic scan command looks like:
wpscan --url https://yoursite.com --enumerate vp,vt,u --api-token YOUR_TOKENThe --enumerate vp flag scans for vulnerable plugins, vt for vulnerable themes, and u for user enumeration. A free WPScan API token gives you 25 API requests per day, which is sufficient for regular scanning of a single site.
Hardening your WordPress installation
Scanning identifies problems — hardening prevents them. The most impactful WordPress security hardening steps in 2026 are:
- Keep WordPress core, all plugins, and all themes updated to their latest versions. Enable automatic background updates for minor releases.
- Remove unused plugins and themes entirely — deactivated plugins still contain vulnerable code that can be reached if the file exists on disk.
- Disable XML-RPC via a server-level block (nginx or Apache) or a plugin like Disable XML-RPC if you are not using it for Jetpack or remote publishing.
- Block user enumeration by preventing access to
/?author=redirects and restricting the WP REST API users endpoint to authenticated requests only. - Add a web application firewall (WAF) such as Cloudflare or Wordfence to block common exploit payloads before they reach your application.
- Move
wp-config.phpone directory above the web root, removereadme.htmlandlicense.txt, and set file permissions so PHP files inwp-content/uploadscannot be executed. - Use strong, unique passwords and two-factor authentication on all WordPress admin accounts. Limit login attempts to block brute-force attacks.
After applying these changes, re-scan with Vuln0x to verify that your security grade has improved and that the flagged issues have been resolved. The scan comparison feature lets you track progress between scan runs directly in your dashboard.
Frequently asked questions
- How do I scan my WordPress site for vulnerabilities?
- Enter your WordPress site URL in the Vuln0x scanner above and click 'Scan free'. Within seconds you will receive a security grade and a prioritised list of findings covering plugin CVEs, theme vulnerabilities, WordPress core version exposure, configuration issues, and missing security headers. No installation is required.
- What is WPScan and how does it compare to Vuln0x?
- WPScan is an open source command-line WordPress security scanner that queries the WPScan Vulnerability Database for known plugin, theme, and core CVEs. It is highly accurate for WordPress-specific findings but requires installation and technical expertise. Vuln0x is a cloud-based alternative that covers WordPress-specific checks alongside a full web security scan — no install needed, with results in under 60 seconds.
- What WordPress vulnerabilities does Vuln0x detect?
- Vuln0x checks for WordPress core version exposure, outdated or vulnerable plugins and themes (cross-referenced against known CVE databases), XML-RPC exposure, user enumeration via the author parameter, directory listing, exposed wp-config.php or debug logs, and standard web vulnerabilities like missing security headers, weak TLS configuration, and cookie security flags.
- Are WordPress sites more vulnerable than other websites?
- WordPress powers over 43% of all websites as of 2026, making it the most targeted CMS. The combination of a large public plugin ecosystem, user-managed updates, and default configurations that prioritise ease of use over security means WordPress sites frequently appear in breach reports. Most attacks are opportunistic and target known, unpatched plugin vulnerabilities — making regular scanning critical.
- How often should I scan my WordPress site for vulnerabilities?
- We recommend scanning your WordPress site after every plugin or theme update, after any WordPress core update, and at a minimum on a weekly basis. New CVEs for popular plugins are disclosed frequently — a weekly automated scan with Vuln0x ensures you are alerted to new exposures before attackers can exploit them.
