External Services

The Security Checks tool (Developer Debug Tools > Tools > Security Checks) connects to the services below when a developer runs a check, and on a daily or weekly schedule if Scheduled Runs is turned on in Settings > Security Checks (off by default). Nothing is sent on page loads.

WordPress.org API (api.wordpress.org): The Core Files Modified check downloads the official file checksums for your WordPress version and language. The Closed or Abandoned Plugins and Themes check looks up each installed plugin and the active theme. Sent: your WordPress version and locale, and the folder names (slugs) of your plugins and active theme. Privacy policy: https://wordpress.org/about/privacy/
WordPress.org downloads (downloads.wordpress.org): The Plugin Files Modified check downloads the official file checksums for each installed plugin from WordPress.org. Sent: the plugin’s slug and version. Privacy policy: https://wordpress.org/about/privacy/
Discord (discord.com): If Discord alerts for Security Checks are turned on, a scheduled run that finds new problems sends the site name, the security score, and the names of the newly failing checks to the webhook URL you enter. Terms: https://discord.com/terms Privacy policy: https://discord.com/privacy

The Security Checks tool also requests this site’s own pages the way a logged-out visitor would, opens a secure connection to this site to read its certificate, and looks up DNS records for this site’s domain and the admin email’s domain with your server’s DNS resolver. These do not send data to any third party.
