WP-CLI Vulnerability Scanner

Check WordPress core, installed plugins and themes for vulnerabilities.

Support Level WordPress tested up to version MIT License Functional Tests

Installation

Global command, automatically

It can be installed as a wp-cli package via git repo which is the most preferred way to install.

wp package install 10up/wpcli-vulnerability-scanner:dev-stable

API Access

WP-CLI Vulnerability Scanner works with WPScan, Patchstack and Wordfence Intelligence to check reported vulnerabilities; you can choose any one of these three to use. You will need to add a constant in your wp-config.php to decide which API service you want to use (by default WPScan API will be used).

To use WPScan API:

define( 'VULN_API_PROVIDER', 'wpscan' );

To use Patchstack API:

define( 'VULN_API_PROVIDER', 'patchstack' );

To use Wordfence Intelligence API:

define( 'VULN_API_PROVIDER', 'wordfence' );

Note: Authentication is not required for the Wordfence Intelligence Vulnerability API ( https://www.wordfence.com/wti-community-edition-terms-and-conditions/ ). VULN_API_TOKEN is not required if using Wordfence as your provider.

For WPScan and Patchstack you will need to register for a user account and supply an API token from the chosen API service. Once you have acquired the token, you can add it as a constant in wp-config.php as follows:

define( 'VULN_API_TOKEN', 'YOUR_TOKEN_HERE' );

Global command, manually

Clone this repo, checkout to stable branch and require wpcli-vulnerability-scanner.php from wp-cli config. E.g. in ~/.wp-cli/config.yml [other config locations]

require:
  - /path/to/this/repo/wpcli-vulnerability-scanner.php

Standard plugin

This repo can be installed as a regular plugin. There is no UI, but the command will become available.

wp plugin install --activate https://github.com/10up/wpcli-vulnerability-scanner/archive/stable.zip

After plugin installation, you can verify the command is in place with wp help vuln

wp theme update $(wp vuln theme-status --porcelain) &> /dev/null

Scheduled/Cron

0 0 * * * wp theme update $(wp vuln theme-status --porcelain) &> /dev/null
0 0 * * * wp plugin update $(wp vuln plugin-status --porcelain) &> /dev/null

0 0 * * * is everyday at midnight. For assistance creating an alternate schedule, check out http://crontab.guru/. For example, 0 0 * * 1,4 runs at midnight every Monday and Thursday.

With email notifications

Included is a sample bash script, includes/vuln.sh. This can be customized and used in a cron job so that you can be alerted when vulnerabilities are found.

  • WPCLIPATH should be the full path to your wp command. The script will attempt to discover this automatically if the given filename does not exist

  • RECIPIENT should be an email address which will receive the notifications

  • SUBJECT is the email subject

This readme does not discuss configuring the mail command on your server. To run a simple test, try

echo "This is the body text" | mail -s "Email subject" [email protected]

Nagios

wp vuln plugin-status --nagios will give output for Nagios monitoring.

Check uninstalled themes and plugins

Check a specific version of a theme or plugin. Example:

wp vuln theme-check twentyfifteen --version=1.1

Or check several at once (cannot accept versions)

wp vuln plugin-check wppizza wordpress-seo
