Vulnerability Overview

A stored XSS vulnerability in the Visualizer plugin 3.3.0 for WordPress allows an unauthenticated attacker to execute arbitrary JavaScript when an admin or other privileged user edits the chart via the admin dashboard. This occurs because classes/Visualizer/Gutenberg/Block.php registers wp-json/visualizer/v1/update-chart with no access control, and classes/Visualizer/Render/Page/Data.php lacks output sanitization.

Technical Analysis

REMEDIATION: Update to version 3.3.1, 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.
