Vulnerability Overview

The Yoast Duplicate Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.2.3. This makes it possible for high-level authenticated users, such as administrators, to inject arbitrary web scripts into administrative pages via several parameters such as 'duplicate_post_title_prefix'. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Technical Analysis

REMEDIATION: Update to version 3.2.4, 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.
