## Description

Collects installed plugins, themes, and WordPress core, then pushes inventory to
your Kistn server for centralized vulnerability monitoring.

**Push flow:**

 1. Preflight — asks the server which slugs need a fresh advisory check and which are
    known-private.
 2. Hash check — skips push if inventory unchanged.
 3. WPScan lookup — queries the WPScan vulnerability database only for stale, non-private
    slugs.
 4. Push — sends packages, vulnerability findings, advisory snapshots, and any newly-
    discovered private slugs.

Private packages (those absent from the WPScan database) are tracked server-side
so subsequent runs never waste WPScan quota on them. When the server later confirms
a package is public, the project owner is notified.

**Configuration** via Settings  Kistn, or via constants in wp-config.php:

define( ‘KISTN_BASE_URL’, ‘https://your-server.example.com’ );
 define( ‘KISTN_PROJECT_ID’,‘
your-project-uuid’ ); define( ‘KISTN_TOKEN’, ‘your-api-token’ ); define( ‘KISTN_WPSCAN_TOKEN’,‘
your-wpscan-api-token’ ); // optional, enables vulnerability lookups

### External services

This plugin can connect to WPScan API to obtain latest security information about
your installation. Use of this feature is optional. To use this feature, you need
a WPScan account and your own API token.

When the feature is used, this plugin sends information about installed WordPress
core, plugins and themes to retrieve latest security advisories about your installed
components. The service is provided by “WPScan”: https://wpscan.com/terms/, https://
automattic.com/privacy/.

## Installation

 1. Upload the plugin ZIP via Plugins  Add New  Upload Plugin.
