The WP Directory Kit plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1.9. This is due to missing or incorrect nonce validation on the 'insert' function. This makes it possible for unauthenticated attackers to update the plugin's settings and inject malicious JavaScript via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

The WP Directory Kit plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to a missing capability check on the 'ajax_public' function in versions up to, and including, 1.2.2. This makes it possible for unauthenticated attackers to delete or change plugin settings, import demo data, delete Directory Kit related posts and terms, and install arbitrary plugins. A partial patch was introduced in version 1.2.0 and an additional partial patch was introduced in version 1.2.2, but the issue was not fully patched until 1.2.3.

The WP Directory Kit plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'search' parameter in versions up to, and including, 1.2.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
