This plugin adds an admin page under the Tools section that reports on any known vulnerabilities in your version of WordPress and any installed themes or plugins.
This information is only visible to administrators (or more precisely, those with the <code>manage_options</code> capability). Subscribers, authors and editors cannot see the data.
<h3>Source</h3>
The information this plugin uses comes from the WPScan Vulnerability Database: https://wpvulndb.com/. It uses a cache and internal throttling to ensure its use of the API is not excessive or abusive.
<h3>Note</h3>
Using this plugin does not guarantee that your site has no vulnerabilities. It also does not absolve you from responsibilities as a site owner to secure your site in other ways, such as SSL or host security. This plugin is only a tool; using it responsibly is up to you.
<h3>WP-CLI</h3>
This plugin registers a WP-CLI command, that allows you to scan from the command line. The response codes are compatible with Nagios (1 for critical error, 2 for warning, 3 for unknown).
<ul>
<li><code>wp vuln scan</code>, to report all known vulnerabilities.</li>
<li><code>wp vuln plugins</code>, to report only vulnerabilities in plugins.</li>
<li><code>wp vuln themes</code>, to report only vulnerabilities in themes.</li>
<li><code>wp vuln wp</code>, to report only vulnerabilities in WordPress core.</li>
<li><code>wp vuln details</code>, to show a more detailed output on known vulnerabilities.</li>
<li><code>wp vuln clear</code>, to clear the internal cache of vulnerability data. This will result in making extra requests to the API, and is probably not needed.</li>
</ul>

Plugin Compatibility Checker

very helpful to check our plugin compatibility


The plugin checks in free version up to php 8.0+ compatibility. Who needs to know if a plugin is compatible with an obsolete version of php ?


A joke ?


The free version gave me a basic idea, but the paid version was way more useful. It caught PHP issues that I wouldn’t have noticed before updating. Glad I upgraded because it saved me time fixing errors later. Definitely more helpful when running sites on newer PHP versions.


Actually prevented a break on upgrade

Scan and check your plugins for PHP and WordPress compatibility. Requires a $1/month Portal subscription to obtain a license key.
