Beschrijving

This plugin integrates with the WPVulnerability API to provide real-time vulnerability assessments for your WordPress core, plugins, themes, PHP version, Apache HTTPD, nginx, MariaDB, MySQL, ImageMagick, curl, memcached, Redis, and SQLite.

It delivers detailed reports directly within your WordPress dashboard, helping you stay aware of potential security risks. Configure the plugin to send periodic notifications about your site’s security status, ensuring you remain informed without being overwhelmed. Designed for ease of use, it supports proactive security measures without storing or retrieving any personal data from your site.

Data reliability

The information provided by the information database comes from different sources that have been reviewed by third parties. There is no liability of any kind for the information. Act at your own risk.

Using the plugin

WP-CLI

You can use the following WP-CLI commands to manage and check vulnerabilities:

  • Core: wp wpvulnerability core
  • Plugins: wp wpvulnerability plugins
  • Themes: wp wpvulnerability themes
  • PHP: wp wpvulnerability php
  • Apache HTTPD: wp wpvulnerability apache
  • nginx: wp wpvulnerability nginx
  • MariaDB: wp wpvulnerability mariadb
  • MySQL: wp wpvulnerability mysql
  • ImageMagick: wp wpvulnerability imagemagick
  • curl: wp wpvulnerability curl
  • memcached: wp wpvulnerability memcached
  • Redis: wp wpvulnerability redis
  • SQLite: wp wpvulnerability sqlite

To configure the plugin you can use:

  • Hide component: wp wpvulnerability config hide <component> [on|off]
  • Notification email: wp wpvulnerability config email <emails> (comma separatted)
  • Notification period: wp wpvulnerability config period <never|daily|weekly>
  • Log retention: wp wpvulnerability config log-retention <0|1|7|14|28> (in days)
  • Cache duration: wp wpvulnerability config cache <1|6|12|24> (in hours)

All commands support the --format option to specify the output format:

  • --format=table: Displays the results in a table format (default).
  • --format=json: Displays the results in JSON format.

Need help?

  • wp wpvulnerability --help: Displays help information for WPVulnerability commands.
  • wp wpvulnerability [command] --help: Displays help information for a WPVulnerability command.

REST API

The WPVulnerability plugin provides several REST API endpoints to fetch vulnerability information for different components of your WordPress site.

  • Core: /wpvulnerability/v1/core
  • Plugins: /wpvulnerability/v1/plugins
  • Themes: /wpvulnerability/v1/themes
  • PHP: /wpvulnerability/v1/php
  • Apache HTTPD: /wpvulnerability/v1/apache
  • nginx: /wpvulnerability/v1/nginx
  • MariaDB: /wpvulnerability/v1/mariadb
  • MySQL: /wpvulnerability/v1/mysql
  • ImageMagick: /wpvulnerability/v1/imagemagick
  • curl: /wpvulnerability/v1/curl
  • memcached: /wpvulnerability/v1/memcached
  • Redis: /wpvulnerability/v1/redis
  • SQLite: /wpvulnerability/v1/sqlite

The WPVulnerability REST API uses Application Passwords for authentication. You need to include a valid Application Password in the Authorization header of your requests.

Example Request with Authentication

curl -X GET https://example.com/wp-json/wpvulnerability/v1/plugins -u username:application_password

Replace username with your WordPress username and application_password with your Application Password.

Extra Configurations

“From:” mail (since: 3.2.2)

If, for some reason, you need the emails sent by the plugin to have a From different from the site administrator, you can change it from the wp-config.php by adding a constant:

define( 'WPVULNERABILITY_MAIL', '[email protected]' );

If the constant is active, it will be visible in the configuration screen.

Force hiding checks (since: 4.1.0)

If you want to always hide a specific component, you can define a constant in wp-config.php. When set to true, the option will be checked automatically in the settings screen and the related analysis will be skipped.

Example:

define( 'WPVULNERABILITY_HIDE_APACHE', true );

Available constants: WPVULNERABILITY_HIDE_CORE, WPVULNERABILITY_HIDE_PLUGINS, WPVULNERABILITY_HIDE_THEMES, WPVULNERABILITY_HIDE_PHP, WPVULNERABILITY_HIDE_APACHE, WPVULNERABILITY_HIDE_NGINX, WPVULNERABILITY_HIDE_MARIADB, WPVULNERABILITY_HIDE_MYSQL, WPVULNERABILITY_HIDE_IMAGEMAGICK, WPVULNERABILITY_HIDE_CURL, WPVULNERABILITY_HIDE_MEMCACHED, WPVULNERABILITY_HIDE_REDIS, WPVULNERABILITY_HIDE_SQLITE.

Cache duration (since: 4.1.0)

By default, data from the API is cached for 12 hours. To change this, define WPVULNERABILITY_CACHE_HOURS in wp-config.php with one of 1, 6, 12 or 24. This value overrides the setting screen and WP-CLI command.

define( 'WPVULNERABILITY_CACHE_HOURS', 24 );

Log rotation (since: 4.2.0)

WPVulnerability stores the most recent API responses so you can review recent calls from the new log tab. Define WPVULNERABILITY_LOG_RETENTION_DAYS in wp-config.php to control how many days of entries are preserved. Supported values are 0, 1, 7, 14 or 28; using 0 disables logging entirely.

define( 'WPVULNERABILITY_LOG_RETENTION_DAYS', 14 );

When the constant is present its value is enforced in the settings UI and through WP-CLI, ensuring consistent log rotation across environments.

Security configuration (since: 4.3.0)

WPVulnerability uses a hybrid detection approach for server software (ImageMagick, Redis, Memcached, SQLite): PHP extensions first (most secure), then shell commands as fallback (most accurate). You can control this behavior using security configuration constants in wp-config.php.

Global disable of shell commands:

define( 'WPVULNERABILITY_DISABLE_SHELL_EXEC', true );

Completely disables shell command usage. Falls back to PHP extensions only. Use for maximum security when accuracy loss is acceptable.

Security mode (standard/strict/disabled):

define( 'WPVULNERABILITY_SECURITY_MODE', 'strict' );
  • standard – Hybrid detection: PHP extensions first, shell commands fallback (default, best accuracy)
  • strict – PHP extensions only, no shell commands (high security, lower accuracy)
  • disabled – No software detection at all (maximum security)

Component whitelist:

define( 'WPVULNERABILITY_SHELL_EXEC_WHITELIST', 'imagemagick,redis' );

Allows shell commands only for specified components. Available components: imagemagick, redis, memcached, sqlite. Use for granular control.

Examples:

Maximum security (no shell commands):

define( 'WPVULNERABILITY_SECURITY_MODE', 'strict' );

Only allow ImageMagick shell detection:

define( 'WPVULNERABILITY_SHELL_EXEC_WHITELIST', 'imagemagick' );

Complete disable:

define( 'WPVULNERABILITY_DISABLE_SHELL_EXEC', true );

All shell commands are hardcoded and validated – no user input is involved. Commands are logged for security auditing.

This is awesome

17 april 2024
Vulnerabilities are listed into your plugins list.You should also being able to receive an automatic email too. It doesn’t work on my system, but email test yes.So awesome plugin anyway!

Perfect

8 april 2024 1 reactie
Exactly what I was looking for ! On the roadmap, it would be nice if : we can chose if we want to receive an email OR not (I may use it as a vuln reminder on the dashboard, as I have other plugins already keeping me informed) we can chose what will be in the email – php or not for exemple (it seems that it is planned, thanks) only receive an email if one the vuln is considered high risk etc.

Security

  • Added CSRF protection via nonces for plugin vulnerability filter links to prevent forced navigation attacks.
  • Added CSRF protection via nonces for theme vulnerability filter links to prevent forced navigation attacks.
  • Plugin and theme filter URLs now include security nonces that are verified before applying filters.
  • Enhanced security against timing attacks on vulnerability enumeration by requiring valid nonces.
  • Enhanced ImageMagick, Redis, Memcached, and SQLite detection with hybrid approach and security controls.
  • All shell commands hardcoded and validated – no user input involved.
  • Shell execution wrapper with complete security checks and logging.
  • Webhook URLs now validated on save: enforces HTTPS and verifies hostname matches allowed domains (Slack: hooks.slack.com, Teams: office.com/office365.com/api.hooks.microsoft.com, Discord: discord.com/discordapp.com).
  • Telegram bot token validation with regex pattern check (format: 123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11).

  • Security audit score improved from 85/100 to 98/100 (comprehensive security audit completed 2026-01-19).

Changed

  • Database error hook now fires the prefixed wpvulnerability_wpdb_last_error action while keeping the legacy hook deprecated.
  • Database update cron now follows the configured cache duration (hourly, 6h, 12h, or 24h).
  • Translations load on init to avoid early textdomain warnings.
  • Vulnerability data now refreshes only via scheduled cron or the manual reload action; admin requests, REST, CLI, notifications, and view rendering no longer trigger API calls to reduce load.
  • Cron scheduling no longer re-queues the update event on every page load; it keeps the configured interval (hourly/6h/12h/24h) unless the schedule changes.
  • REST API now requires administrator capabilities for session or application password access.
  • Admin reset and test email actions enforce admin capabilities.
  • API client timeouts corrected to 2.5 seconds to avoid long hangs.
  • Slack/Teams webhooks restricted to allowed HTTPS hosts to limit SSRF exposure.
  • Tools tab adds a full reset action that clears all plugin data, restores defaults, and reloads from the API.
  • Complete redesign of the admin settings interface with modern card-based layout for all tabs: Security, About, Logs, Tools, Analysis, and Notifications.
  • Settings tabs now feature visual component cards with icons, improved spacing, color-coded status badges, and responsive grid layouts for enhanced usability.
  • Complete redesign of the Dashboard widget with modern, clean interface replacing the basic list layout.
  • Dashboard widget now features prominent status badge with three states: “All Clear” (green, 0 vulnerabilities), “X Issues Found” (yellow, minor issues), “X Critical Issues Found” (red, Core/PHP vulnerable or 5+ total vulnerabilities).
  • Dashboard widget displays last check timestamp with human-readable format (“X minutes ago”, “X hours ago”) and “Refresh Now” link.
  • Dashboard widget shows attractive empty state with centered green checkmark when no vulnerabilities are detected.
  • Dashboard widget separates components into two clear sections: “WordPress Components” (Core, Plugins, Themes) and “Server Software” (PHP, web server, database, etc.).
  • Dashboard widget uses color-coded badges: green for secure (✓ 0), yellow/red for vulnerabilities (✕ N) with consistent design.
  • Dashboard widget displays server software in 2-column grid layout for better space utilization.
  • Dashboard widget shows vulnerable plugin/theme lists indented below their respective components.
  • Dashboard widget uses inline CSS with modern styling: flexbox layouts, proper spacing, WordPress admin color palette, improved typography (13px components, 12px meta).
  • Dashboard widget footer includes links to Site Health and Settings with visual separation.
  • All CSS class names, HTML IDs, and JavaScript references changed from short prefix .wpv- to full prefix .wpvulnerability- to prevent naming conflicts with other plugins and themes (affects 73+ unique classes across admin panels).
  • All inline CSS from admin panels moved to external assets/admin.css file for better performance and cacheability (~1084 lines extracted from 14 style blocks across single-site and multisite admin panels).
  • License updated from GPL2+ to GPL3+.

Fixed

  • Saving partial forms (e.g., log retention) no longer resets other notification settings to their defaults; existing values are preserved unless explicitly changed.
  • Network (adminms) settings now preserve existing values when saving individual forms and keep notification scheduling consistent.
  • Cache column in Component Detection (Debug tab) now correctly displays cache expiration time by properly decoding JSON-encoded timestamps from database.
  • Database detection now properly distinguishes between MariaDB and MySQL instead of always showing “MySQL”.
  • Multisite network admin forms (Notifications, Analysis, Configuration) now submit correctly by using proper network admin URLs and nonces instead of incompatible Settings API methods.
  • All form submission buttons in multisite admin now include proper name attribute (wpvulnerability_submit) for backend processing.
  • Delete logs form in multisite now uses network_admin_url() instead of single-site admin_url() for correct URL generation.
  • All multisite form nonce verifications now match their corresponding form nonce fields (reset, email, repair cron, delete logs) instead of using generic nonce.
  • Security tab in multisite network admin now works correctly by including all required helper functions (wpvulnerability_display_security_status, wpvulnerability_display_detection_methods, wpvulnerability_display_security_logs) instead of calling undefined single-site functions.
  • Tools tab buttons in multisite network admin no longer show “nonce expired” errors by submitting forms to the same page (action=””) instead of explicit URL paths that fail referer validation.
  • Delete All Logs button in Logs tab no longer shows “The link you followed has expired” error by using empty form action (action=””) in both single-site and multisite admin panels.
  • Logs tab pagination now displays horizontally instead of vertically by properly targeting list elements (ul with inline-flex) and individual page links (a and span within li) to work correctly with WordPress paginate_links() ’type’ => ‘list’ output.
