Sitevorx for WordPress Plugin Directory

Sitevorx is a lightweight, all-in-one WordPress plugin that helps you optimize performance, harden security, and manage your website from a single, modern dashboard. No bloat, no external dependencies — just the tools you need.

Security Center (NEW in 1.1.0)

Security Score Dashboard: A single 0–100 score that summarizes the hardening state of your site, with prioritized recommendations.

Core Integrity Checker: Compares every WordPress core file against the official api.wordpress.org MD5 checksums to detect modified, missing, or extra files.

HTTP Security Headers: One-click enable X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Permissions-Policy on the frontend.

Login Honeypot: Invisible bait field on wp-login.php that silently rejects spam bots without affecting real users.

User Enumeration Protection: Blocks ?author=N probing and the public REST /wp/v2/users endpoint for non-logged-in visitors.

Login Notification: Emails the administrator whenever an account with manage_options logs in successfully (1-hour cooldown per IP).

Login Attempt Limiter: Lock out IPs after repeated failed login attempts, with configurable threshold, lockout duration, and IP allowlist.

Secret Login URL: Hide the default wp-login.php behind a custom keyword.

Google reCAPTCHA v2 / v3: Protect the login form from bots, with a configurable v3 score threshold.

Disable XML-RPC and Disable File Editor: Block DDoS / brute-force vectors and stop code editing from the dashboard.

Speed Optimization

Heartbeat Throttle: Slows the Heartbeat API to 60 seconds instead of disabling it, preserving autosave and post-locking.

System Tweaks: Lazy load images, limit post revisions, allow safe SVG uploads (with XXE-hardened sanitizer).

Database Cleanup: Remove revisions, spam comments, and expired transients in one click.

Malware Scanner: Scan your entire codebase and database for suspicious injections.

Send emails via Gmail (App Password) or a custom SMTP server (SSL/TLS).

External Services Google reCAPTCHA (v2 and v3) Sitevorx can optionally integrate with Google reCAPTCHA (v2 checkbox or v3 invisible / score-based) to protect the WordPress login form. This feature is disabled by default and only works when an administrator explicitly enables it, selects a version, and provides valid Google-issued API keys.

When enabled, the plugin loads the Google reCAPTCHA JavaScript on the login screen and sends the generated verification token to Google’s verification endpoint (https://www.google.com/recaptcha/api/siteverify) during login validation. For v3, the configurable score threshold (filter sitevorx_recaptcha_v3_score_threshold, default 0.5) is compared against Google’s returned score.

WordPress.org Core Checksums API The Security Center → Kiểm Tra Toàn Diện → WordPress Core Integrity check (off by default; runs only when the admin clicks “Kiểm tra”) fetches the official MD5 checksums for the installed WordPress version from WordPress.org so it can flag modified or missing core files.

Verification endpoint: https://api.wordpress.org/core/checksums/1.0/

Request payload: only the installed WordPress version string (e.g. 6.4.2) and the locale en_US. No site URL, user data, or content is sent.

Operated by: WordPress.org

Terms of Service: https://wordpress.org/about/privacy/
