Comprehensive security analysis for WordPress websites
A WordPress Security Checker is an automated scanning tool that analyzes WordPress websites for common security vulnerabilities, misconfigurations, and potential attack vectors. WordPress powers over 40% of all websites on the internet, making it the most popular content management system and a prime target for attackers. Our free online scanner performs 14 comprehensive security checks to help you identify and fix vulnerabilities before they can be exploited.
The WordPress Security Checker at Jayax.dev examines your site for exposed files, enabled services, missing security headers, user enumeration risks, SSL/TLS configuration issues, and much more. Each check produces a detailed finding with severity rating, evidence, and actionable remediation steps to help you harden your WordPress installation.
WordPress sites face a wide range of security threats. Understanding these vulnerabilities is the first step toward protecting your website and your visitors.
Our WordPress Security Scanner performs a systematic series of non-invasive checks against your target URL. Each check is designed to identify a specific vulnerability or misconfiguration without causing any harm to your website. The scanner operates entirely in the browser, sending standard HTTP requests similar to what a normal visitor would generate.
After completing all 14 checks, the scanner calculates an overall security score from 0 to 100. The scoring system weights findings by severity: Critical issues deduct 15 points, High issues deduct 10 points, Medium issues deduct 5 points, and Low issues deduct 2 points. Informational findings do not affect the score. The final score is mapped to a letter grade from A+ (97-100) to F (0-59).
A score of 90 or above indicates a well-hardened WordPress installation with minimal exposure. Scores between 70 and 89 suggest moderate security with some areas needing attention. Below 70 indicates significant vulnerabilities that should be addressed promptly. A failing grade (below 60) means your site has critical security issues that require immediate action.
Beyond fixing the issues identified by our scanner, following these WordPress security best practices will significantly improve your site's security posture.
Our WordPress Security Checker goes beyond simple vulnerability detection. Each finding includes an AI-powered remediation feature that provides personalized, detailed fix instructions. Click the "Get AI Fix" button on any individual finding, or use the overall "AI Analysis" button to receive a comprehensive, prioritized action plan for all identified vulnerabilities. The AI considers your specific configuration and provides code examples, plugin recommendations, and step-by-step instructions tailored to your findings.
Regular security scanning should be part of your WordPress maintenance routine. We recommend scanning your site in these situations:
By regularly using the WordPress Security Checker at Jayax.dev, you can maintain a strong security posture and protect your website, your users, and your data from common WordPress attacks. Start scanning today to identify and fix vulnerabilities before they can be exploited.
A WordPress Security Checker is an online tool that scans your WordPress website for common security vulnerabilities and misconfigurations. It checks for exposed files, missing security headers, outdated versions, user enumeration, and other issues that attackers could exploit. The tool provides a security score and detailed remediation steps for each finding.
The scanner sends HTTP requests to common WordPress endpoints and analyzes the responses. It checks for exposed configuration files, accessible admin panels, enabled XML-RPC, REST API exposure, directory listing, login error messages, default files, CORS misconfiguration, user enumeration, wp-cron exposure, author ID enumeration, missing security headers, and SSL/TLS configuration. Each check returns a severity rating and remediation advice.
Yes, the security scan is completely safe. It only performs read-only checks by sending standard HTTP requests that any browser would make. It does not attempt to exploit vulnerabilities, modify files, or perform any destructive actions. The scan is equivalent to manually checking these URLs in your browser.
The security score ranges from 0 to 100, starting at 100 and deducting points based on findings: Critical issues deduct 15 points, High issues deduct 10, Medium issues deduct 5, and Low issues deduct 2. The score is converted to a letter grade from A+ (97-100) to F (0-59). A higher score indicates better security posture.
XML-RPC is a remote procedure call protocol that WordPress uses for features like pingbacks and remote publishing. When enabled, attackers can use it for brute force attacks by sending hundreds of login attempts in a single request, DDoS amplification through pingback abuse, and system fingerprinting. Unless you specifically need it for remote publishing or third-party apps, it should be disabled.
Security headers are HTTP response headers that instruct browsers to enable built-in security protections. Important headers include X-Frame-Options (prevents clickjacking), X-Content-Type-Options (prevents MIME sniffing), Content-Security-Policy (prevents XSS), Strict-Transport-Security (enforces HTTPS), Referrer-Policy (controls referrer information), and Permissions-Policy (controls browser features). Missing headers leave your site vulnerable to various attacks.
User enumeration is a technique where attackers discover valid WordPress usernames through the REST API (/wp-json/wp/v2/users), author archives (?author=1), or login error messages. Once attackers know valid usernames, they can launch targeted brute force attacks. To prevent this, disable the REST API users endpoint, block author queries, and use generic login error messages.
WordPress displays its version number in the HTML meta generator tag, RSS feeds, and script/style file queries. To hide it, add `remove_action('wp_head', 'wp_generator');` to your theme's functions.php. Also remove version numbers from scripts and styles, and hide the readme.html file which also contains version information.
Cross-Origin Resource Sharing (CORS) misconfiguration occurs when a server allows requests from any origin (wildcard *) or reflects the requesting origin back in the Access-Control-Allow-Origin header. This can enable cross-site attacks where malicious websites can interact with your WordPress site on behalf of authenticated users. Configure CORS to only allow trusted, specific origins.
The wp-cron.php file handles scheduled tasks in WordPress. When publicly accessible, anyone can trigger it, potentially causing performance issues through repeated execution. Additionally, if wp-cron is disabled but the file is accessible, it could indicate misconfiguration. Best practice is to disable default wp-cron by adding `define('DISABLE_WP_CRON', true);` to wp-config.php and set up a server-side cron job instead.
You should scan your WordPress site at least monthly, after any major changes (theme updates, plugin installations, server migrations), and immediately if you suspect a security breach. Regular scanning helps catch new vulnerabilities before attackers can exploit them. Consider setting up automated monitoring for continuous protection.
Start by addressing Critical and High severity findings first. Common fixes include installing an SSL certificate, removing exposed files (readme.html, wp-config.php access), disabling XML-RPC, adding security headers, preventing user enumeration, and updating WordPress to the latest version. Use a security plugin like Wordfence or Sucuri for ongoing protection, and consider implementing a Web Application Firewall (WAF).
