MainWP Vulnerability Checker v4.1

MainWP Vulnerability Checker extension uses either the free MainWP NVD API or the paid WPScan Vulnerability Database API to bring you information about vulnerable plugins and themes on your Child Sites so you can act accordingly.


Get information on vulnerable plugins and themes and what the issues are, directly from your MainWP Dashboard.

  • The Vulnerability Extension gathers the latest information in real-time.
  • Get notified about vulnerabilities on your websites.
  • Update vulnerable plugins.
  • Delete vulnerable plugins.


This is a free API provided by the National Institute of Standards and Technology (NIST) in the U.S. Department of Commerce.

The NIST NVD is the U.S. government repository of standards-based vulnerability management data represented using the Security Content Automation Protocol (SCAP). This data enables the automation of vulnerability management, security measurement, and compliance. The NVD includes databases of security checklist references, security-related software flaws, misconfigurations, product names, and impact metrics.


The WPScan Vulnerability Database is an online browsable version of WPScan’s data files used to detect known WordPress core, plugin, and theme vulnerabilities. This database compiles by the WPScan Team and various other contributors since WPScan’s release. BruCON’s 5by5 project funded the development of the WPScan Vulnerability Database.
