Vulnerability Overview

The Top Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the tpbr_message,tpbr_btn_text,tpbr_btn_url, and tpbr_color parameters. This allows authenticated users with administrator-level permissions 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.

Technical Analysis

REMEDIATION: Update to version 3.0.4, 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.
