Vulnerability Overview

The Custom Post Type UI plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'label' parameter during custom post type import in all versions up to, and including, 1.18.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses the Tools → Get Code page.

Technical Analysis

REMEDIATION: Update to version 1.18.2, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
