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.
