Vulnerability Overview

The Custom Post Type UI for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.13.4 . This is due to missing or incorrect nonce validation in the cptui_render_debuginfo_section function. This makes it possible for unauthenticated attackers to exfiltrate debug information gathered by the plugin via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. The information contains a list of installed and activated themes and plugins, version information for PHP, MySQL and Web Server.

Technical Analysis

REMEDIATION: Update to version 1.13.5, or a newer patched version --- IDENTIFIER: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
